What is frequency? Frequency is the number of cycles of a repeating signal. The unit of frequency is measured in hertz. Each hertz is equal to one cycle of an event in seconds.
For a frequency to be considered an audio frequency it has to be between 15 Hz and 20000 Hz. A radio frequency will range from 20 kHz to 1 terahertz.

A medium for radio frequency will be air and metal. Air will not conduct electricity so the displacement won’t happen. When it comes to infinity value, air will become resistant and only some current flow will go through. Metal is an electricity conductor. This means that the flow will be based on the resistance of metals and the components with in the metal.

What is analogue modulation? Is the information which is applied to the carrier signal. This is usually with radio signals. The amplitude modulation will change any frequency of the signal.

Frequency Modulation is the frequency of the Carrier can wave at the input signal with the level use multiple methods
When comparing the modulation we can show that both use the same method. The only difference is that digit.

While this process is going on the digital modulation can use multiple times. Digital will also apply filters to interfering data. The disadvantage is it will give communication

Frequency Response

...Introduction This lab deals with the concept of frequency response. During steady state, sinusoidal inputs to a linear system will generate sinusoidal responses of the same frequency, but of different amplitude and phase angles. This is due to a time lag between input and output generated. These differences are functions of frequency. In this experiment, the frequency response test is used to identify the (linear) dynamics of a plant. It is performed by inputting a sinusoidal signal and comparing it with the sinusoidal output. Objective of Experiment 1. To perform a frequency response test on an aircraft electro-hydraulic servo-actuator, hence determining the phase and gain margins of the servo-actuator. 2. To verify that increasing the gain by the gain margin causes instability. Equipment and Apparatus 1. Electro-hydraulic servo-actuator 2. Amplifier unit 3. Oscilloscope (CRO) 4. Function generator (FG) 5. Hydraulic power supply (outside laboratory) Background of Experiment This experiment utilizes a servo mechanism which is an automatic device that takes advantage of error-sensing feedback to correct and amplify the signal. The servo system comprises of a servo-actuator and an amplifier unit. In aircrafts, a similar system is used to convert electrical autopilot voltage outputs into a proportional mechanical movement. The mechanical movement is linked to the control rods, which controls the equipment the pilot uses to move the......

Radio-Frequency Identification Essay

...R.F.I.D. (Radio-Frequency Identification) RFID is the wireless non-contact use of radio-frequency electromagnet fields to transfer data. RFID tags are used in many industries to enter or exit buildings as well as buy certain things (mostly use in the government). It can also be attached to cash, clothing, and everyday possessions (such as cell phone, Laptops, desktop computers, tablets, etc.). Let me give you some history about where this technology came from In 1945 Leon Theremin invented an espionage or spying tool for the Soviet Union which retransmitted incident radio waves with audio information. Sound waves vibrated a diaphragm, which slightly altered the shape of the resonator that modulated the reflection radio frequency. So basically Leon Theremin created the processor for the RFID technology because it is being energized and activated by waves from an outside source. RFID uses signaling between the reader and tag is done in several different incompatible ways its all depending upon the frequency band being used. Tags operate on LF and HF bands, which use small radio waves to transmit signals. In the near electromagnetic field region the tag is closely combined electronically with the transmitter in the reader. The tag can increase the electromagnetic field created by the reader by changing the electrical loading. By changing the relative loads higher or lower the tag produces a change that the reader can......

Frequency, Wave Lenght and Wave Velocity

...Abstract: The purpose of this experiment was to verify the relationship between frequencies, wave length and wave velocity of a transverse wave on a string, as well as the relationship between the spring tension and the number of standing waves formed. Two different strings used in this experiment are white and black in colour; the µ1 value calculated for the white string is 2.73 x 10-3 ±0.00055kg/m with an uncertainty of ±8.2932 x 10-5 kg/m while the µ2 value calculated for the black string is 1.38 x 10-3 kg/m with an uncertainty of ±8.6492 x 10-5 kg/m. However, the actual linear mass density µ0 of the white spring calculated is 2.87x10-3kg/m; compared to the experimental linear mass density µ1, the difference in error was 4.88%, however, the mass of the black spring was too small to be weighted therefore the actual linear mass density µ0 was unable to be calculated, so cannot be compared to the experimental linear mass density µ2. Introduction: A wave can be described as a disturbance that carries energy and travels through a medium form one location to another. Waves can be classified into two types, transverse waves and longitudinal waves. This experiment was based on transverse wave and can be described by the position of the particles at a particular time as well as how the position changes with time. Transverse wave can also be considered as a wave that remains at constant position. Wave produced by a vibrator travels down a string and......

The Effect of Different Music Frequencies on Society

...The Effect of Different Music Frequencies on Society BS/P-001 09-05-2013 Although not everyone listens to music regularly, it can (music) have a positive or negative effect on the listener depending on the frequency. Music tuned to A=432Hz can have a healing effect, while music tuned to the frequency of 440Hz can have the opposite effect. They have both proven to be a powerful influence depending on how they are used. According to some sources, Nazi Propaganda Minister Joseph Goebbles set the 440Hz standard in 1939, which was later adopted by the International Standards Organization as early as 1953. Music can have a positive effect on society depending on the frequency. For example, listening to music which ash been tuned to the international standard frequency of 440Hz can cause a shift in consciousness toward more negative attributes of violence, anti-social behavior, aggression and negative emotions. In contrast, music which has been toned to the more natural frequency of 432Hz, which has been considered the pulse of the universe, when listened to, has been known to generate profound healing on all levels and spiritual well-being. Music has such a powerful influence that it has Benn used for everything from selling products to making money for entertainers. While in public, whether walking down the street, on the bus or on the subway, you see people listening to music on ipods, ipads and mp3 players and music is downloaded daily from websites that have the......

Radio Frequency Identification (Rfid) Technology in Construction Industry

...Radio frequency identification (RFID) technology is currently being used in such areas as agriculture, athletics, manufacturing, security and law enforcement, and transportation, but few applications have been developed that are related to the construction and facilities operations environment. Lack of standardisation, high costs of implementation, slow technology development and deployment risks, and the lack of skilled labour are all contributors currently preventing the adoption of new RFID technologies in the construction industry. The RFID technology can help improve data accuracy by tracking products through supply chains and by identifying products and items/objects at specific points through Automatic Identification (Auto-ID). The technology enables the detection and identification of tagged objects through the data it transmits. Objective of this topic ‘RFID IN CONSTRUCTION’ is to get an overview of the present application of RFID technology in Construction. Radio Frequency IDentification (RFID) is an old technology which was already in use for recognition for anti-aircraft gun shooting in World War. Since then RFID has been taken into use for many other purposes, i.e. securing against theft of goods, bridge crossing fees, car keys etc. The new importance of RFID is connected to certain measures which a group of the world’s biggest retail chains and brand suppliers initiated under the name of Global Commerce Initiative at the end of the 1990’es.

Frequency Response

...Abstract There is a growing importance for the studies of frequency stability and control of power system with increasing levels of wind power penetration, especially in United States with a goal of 20% or more by 2030. The increasing penetration of wind in to existing synchronous based generation capacity requires the modifications in the procedures of grid frequency control as wind turbine units fail to provide inertial support and primary control reserves during the initial and later stages of frequency events respectively. Therefore, it is necessary for the wind turbines to emulate the response of current synchronous based generation capacity so as to make the power system reliable. This type of response can be introduced by control schemes developed. This report provides a literature review of the frequency control basics and controller schemes used. And also it provides an overview of the basic concepts related to the effects of wind generation on frequency behavior of the power system network. Introduction Frequency stability and control very much dependent on active power balancing is a major research topic concerned with grid integration of large wind farms. The instability of frequency occurs when power system fails to maintain it within particular limits under normal conditions. Active power imbalance indicates the variations in frequency and consequently the constancy of frequency represents the quality of power supply. Such an imbalance can be......

Cis 513 Unicode & Frequency Hopping Spread Spectrum (Fhss)

.... CIS 513 Assignment One Unicode & Frequency Hopping Spread Spectrum (FHSS) Name School Class Professor Dates Abstract Unicode provides a standardized means for text in nearly any language to be shared across the Internet. Frequency Hopping Spread Spectrum is a means by which transmissions “hop” between a variety of frequencies, lessening the transmission’s vulnerability to outside sources. Assignment One Unicode Our world is increasingly shrinking as new technologies are bringing people and their cultures in closer contact with each other. Two technologies that are helping make this happen are wireless computing in all its various forms and Unicode. To understand how important Unicode is to the future of the Internet and computing, first we need to understand why Unicode was developed. Its main predecessor, the American Standard Code for Information Interchange (ACSII), which is “stored as 1 byte (8 bits) in binary code.” (Olenewa, J. & Ciampa; M. (2007) However, “one of the limitations of ASCII is that there are not enough codes for all the symbols used by foreign languages.” (Olenewa, J. & Ciampa, M.; 2007) Additionally, ACSII is only useful for up to 128 different codes. Unicode breaks this barrier by using 2 bytes (16 bits) in order to represent nearly all of the languages of the world. From this it’s not too much of a leap to see that using Unicode is useful to global businesses in a variety of ways. As these global businesses......

P.Sudheesh, Dr.M.Jayakumar Assistant Professor, Associate Professor, Dept. of ECE, Amrita Vishwa Vidyapeetham, Ettimadai, Coimbatore – 641105. 1 2 ABSTRACT Orthogonal Frequency Division M ultiplexing (OFDM ) has been accepted as the modulation scheme of choice for the next generation high-speed wireless communication systems due to the advantages that it offers like high spectral efficiency, resistance to multipath fading and resistance to frequency selective fading. M oreover, it lends itself to simple channel equalization. Conventional single carrier systems do not provide such advantages and hence, OFDM would almost ubiquitously be used for high speed wireless data transmission. However, the main drawback of such systems over single carrier systems is that in the presence of noise, there is an increased computational complexity at the receiver end to decode the data. In this paper, a low complexity detection algorithm is proposed for OFDM systems. M aximum likelihood detection is taken as the baseline detection algorithm and the proposed algorithm is compared......

Ac Operational Amplifiers

...investigation which comprises of testing three operational amplifier circuits with AC signals. The three types of circuit include the integrator, the AC inverting amplifier and the AC non-inverting amplifier circuit. The integrator circuit was tested with a square-wave and a sinusoidal wave input signal at 1kHz frequency. The results showed that the square-wave input signal produced a triangular wave output whereas the sinusoidal input produced a sinusoidal output signal with a positive 90 degree phase shift. Both output signals were showed to be the integral of their relative input signals. The output voltage gain of the AC inverting and the AC non-inverting amplifier circuits were tested with a frequency range of 100Hz to 10kHz. The results were plotted on a logarithmic scaled graph which showed that both amplifiers acted like high-pass filters, each amplifier achieving its maximum gain set by the specification at higher frequencies nearer to 10kHz. The only difference between the two op-amps was that the AC inverting amplifier achieved negative gain in comparison to the positive gain achieved by the AC non-inverting amplifier. For further investigation, the frequency was increased above 10kHz for the AC inverting amplifier circuit which showed a linear fall in gain, which was explained by the theory of slew rate limitation. In conclusion, the three operational amplifiers operated as expected. Table of Contents ABSTRACT 1 1. INTRODUCTION 4 2. THEORY 4 2.1.......

Basic

...The Basic Parts The Basic Parts There are just five basic parts in a radio frequency communication system. These are: * Antenna * Amplifier * Filter * Mixer * Source These five parts are then put together to do one of two basic functions: transmit or receive. The name of the resulting device is a radio. The radio also may go by many other names based on marketing considerations or its specific role in the wireless network. A radio is used to send and receive a signal that flows through the air as a series of electromagnetic waves. Radios can take on many different forms. As such, it is not always easy to identify them. When transmitting or receiving, the goal is to produce a perfect sine wave, of the exact size required, at only one frequency. A block diagram of the basic parts looks like the following. For a transmitter: This diagram shows a conceptual layout of a typical transmitter. Included in it are six elements. They are, in order: source, amplifier, source, mixer, filter, high-power amplifier, and antenna. For a transmitter, the signal is generated by the source. The mixer changes the frequency of the signal. The filter removes undesired frequencies. The amplifier increases the signal. The antenna transforms the electrical current into a radio wave. The other amplifier provides the electrical signal. It also feeds into the mixer. For a receiver: This diagram shows a conceptual layout of a typical receiver. Included in it are......
