ANALOG AND DIGITAL COMPARISON 2
Analog and Digital Comparison The improvements in technology have impacted people’s everyday lives immensely. Particularly, in the manner those individuals communicate. Telecommunications has seen a vast change over the years that can date back to when the telegraph was invented by Samuel F.B. Morse in 1832. In order for there to be successful communication two specifications must be fulfilled. First is the transmitter and receiver must understand each other. The second requirement is the ability to identify errors while they’re in occurrence and have a solution to fix the errors. Communication is carried by data devices through transmission lines; transmission lines come in the form of circuits, channels, lines, trunks, and virtual circuits. The two forms of transmission are analog and digital transmission. Analog transmission is the traditional form of sending and receiving signals in telecommunications. Analog signals are in the form of waves that are composed of amplitude and frequency. Analog transmissions are sent along single channels. Before the introduction of digital transmission, analog transmission was used for radio, television, and telephones. Analog transmission duplicates the sound or image from where it was sent. Voice signals are transmitted as sound waves; the duplicate of the sound wave is transmitted as electricity through a wire and then converted once again into a sound wave to the receiver. The same process takes place with television. Analog transmissions have low bandwidth; therefore they cannot support high-speed data. Analog transmission also tends to accumulate more noise or errors. The reason is because signal wave amplify sound, so...

Analog and Digital Comparison

...Analog and Digital Comparison Technologies for analog-to-digital and digital-to-analog conversions There is no actual all analog or all digital telecommunications going on technologically today (Goleniewsk & Wilson Jarrett, 2007, Chapter Chapter 1, Analog Versus Digital Transmission). One day, developers hope to make the network 100% digital. Connecting to the internet or just making a call to your mother two states over is a mixture of both when it comes to communicating from one terminal to the next. That being said, it takes codecs and modems for a successful conversion to occur. Say you are calling another state from a land line. This call will start out analog at your telephone and then must be converted to digital. When you pick your phone up, it connects to a codec. Your voice can range from 100Hz to 10,000Hz depending on many factors. The average Hz a phone company will allot is 4,000 which works for virtually all people. Codec is short for coder-decoder and it works by minimizing the amount of bits per second that will carry the voice to the multiplexer. In the case of a cellular network, the data will have to be compressed even further so that the most efficient transmission can occur. The codec will then transfer the data to a multiplexer. This particular multiplexer is a TDM (time division multiplexer). This will allow for one channel to be open at a time....

Analog and Digital Comparison Paper

...Analog and Digital Comparison Paper Amanda Dyer, Derick Campos, Jesse Ford, Mehran Gerami, Nicolas Monteiro, Wendell Taylor NTC/362 October 15, 2015 Richard Swafford, Jr. Analog and Digital Technology: A Comparison Analog and digital are two different types of signals used to transmit audio or visual information from one place to another. Analog signals are continuous, meaning that there are no breaks or interruptions and digital signals are not continuous, they use specific values to represent information (Strickland, 2008). Analog transmissions are sent via electronic pulses of varying amplitude, while digital transmissions are converted into binary format to represent two individual amplitudes. Analog is cheap and has been used quite some time now, but the biggest issue with analog signals is the limitation of data that can be transmitted. Nowadays almost all equipment being produced is digital based. Analog to digital conversions or A/D conversions is the process of changing a continuous variable signal to a multi-level signal without altering the vital contents or the information or data. A prime example of a telecommunication that uses this form of conversion is a telephone modem. Voice communications vary in range and are not in binary form, so these analog signals must be translated into digital signals. Digital to analog conversions or DAC is the conversion of binary code to analog signal....

Comparison of Analog and Digital Technology

...Comparison of Analog and Digital Technology NTC362 The process of Analog to Digital Conversion starts with the transmission of the original information, followed by the modulation and then reception at the receiver and making sure that there is no factor of signal degradation and noise. “The binary signal is made up of two symbols namely binary digits or bits 1 and 0. If there is no influence of noise and distortion during transmission, the binary information will be the same. The change in the signal is being measure at the receiver. Encoding is needless if the information to be transferred has already been converted in binary form just like in data communications. In contrary, voice communication through telephone is not in binary form. These are analog signals that vary in range of values and therefore must be converted to digital form before it is being used in digital communications system.” (T. T. (2011). Digital signal to analog signal conversions involve the use of DAC (Digital-to-Analog Converters). DAC accepts the discrete binary values and converts them into continuously-varying values of analog signal. This conversion may affect the fidelity of the signal if the process was not properly monitored. Analog telephone lines, most commonly called POTS lines, uses separate lines (e.g. standard phone and fax lines, alarm lines, etc.) from the digital equipment lines (e.g. PBX)....

A Comparison of Digital and Analog Technologies

...Introduction Analog-to-Digital and Digital-to-Analog Conversions Telecommunications relies on the transmission of data through different mediums such as a telephone, radio, television, among others. These transmissions are done through two signal types, which are analog and digital. Analog is the first type of transmission type because it is the older and has been around for a lot longer than digital. On the other hand, even though digital transmission is a younger generation, it is currently use in more devices than analog. Each signal has its advantages and disadvantages, but in most scenarios, both need to work together to create an effective transmission. Technologies that convert analog into digital and vice-versa have been created for this purpose. Converting the signals allows for a more cohesive environment because each can be adjusted to work on devices or mediums not made for them originally. The next part of this paper covers the technologies use to convert these signals. Analog to Digital Conversion In order for this conversion to take place, an analog-to-digital converter (ADC) is necessary. This component is essential because it is responsible for receiving the analog signal as input and sending a digital signal as output. The ADC receives an analog signal such as sound, voice, or voltage and transforms that signal into a binary output....

Analog & Digital Comparison Paper

...An analog signal is defined by moving nonstop along the amplitude and frequency line. An example is talking through the telephone, when a person speaks in the microphone the pressure from the mouth changes and collects into the handset and is augmented and turned into current. The rise and fall in the current are the analog of the voice pattern. The digital signal is different form an analog because a digital signal is not as complex, a digital transmission uses pulses representing one bits and zero bits. Presently we use a combination of both analog and digital networks. In different areas of the network it is necessary to use analog and digital. A codec, which is a combination, is the words “coder” and “decoder” converts the analog signal to digital. There are various types of codecs for various purposes. In the “Public switched telephone network” (PTSN), there are specific codecs that will help reduce the amount of bits that are transmitted digitally in the PTSN. On a cell network there are codecs that condense the auditory voice to maximize the ability to transmit over the network. Video codec for communication require specific compression capabilities in order to send videos through the network efficiently. The word modem, which is a combination of the words "demodulate" and "modulate" is specific device that converts analog to digital signals over the network. However this conversion has many problems and proves to be the weakest link in the network....

...Analog and Digital Comparison Learning Team D: Juan C. Godinez, Luke Wade, Jonathan Selinksi NCT/362 March 16th, 2015 Richard Bohn Analog and Digital Comparison Data, media, networking and transfer technology has evolved immensely throughout the years. When it comes to transmissions, two prerequisites must be satisfied to have successful communication. The first prerequisite is understandability. The transmitter and receiver must speak the same language. The second prerequisite is the capability to detect errors as they occur and to have some procedure for resolving those errors. (Goleniewski, L., 2007). Picture this similar to the different languages people can speak all over the world. Without proper translation and understanding, the conversation is pointless; this analogy is similar for analog and digital transmissions. Beginning with an analog signal, which is a continuous variable along amplitude and frequency. Analog circuits need to have a defined frequency band in which it operates. Different modulation schemes can vary the speed in which they operate, the quality of wire they require, the immunity to noise, and their overall complexity. The variety of modulation schemes in existence can be a disadvantage as this means many incompatibilities can exist within a single application. Such modulations include: * Amplitude modulation (AM) - modem relies on amplitude and associates high amplitude/zeros with low amplitude....

Analog Comparrison

...Analog and Digital Comparison Paper Team A NTC/362 Dr. Jose Gotay November 11, 2014 An analog signal is a moving nonstop amplitude and frequency line. A good example of an analog signal is when a person is talking on a cell phone, when the person speaks into the microphone on the cell phone the pressure from the mouth is stored in the phone and creates a current. The rise and fall of the current is the analog voice pattern signal. The digital signal is less complex than the analog signal; because the digital signal uses binary code or zero and one bits to transmit signals. Analog transmissions can be converted into digital transmissions and vice versa. Conversions are made possible by codecs and modems. Codecs combine analog-to-digital conversion and digital-to-analog conversion. Some codecs are able to reduce the amount of bits per second that are required for voice to be transmitted digitally. Compression is required when converting cell phone networks and video communications because of the limited spectrum and channels (Goleniewski & Jarret, 2007). A modem controls analog signals to encode digital data and demodulates the signal to decode the information sent. An analog signal works with computers to transform the digital data into electrical signals through a telephone channel and then demodulate the signals back into digital data....

...Analog and Digital Comparison Paper Current technology utilizes many different types of transmission cable such as fiber optics, coaxial cable, and twisted pair copper wire. These different types of cables use different communications techniques that maximize their efficiency. For instance, fiber optics can carry digital signals over long distances without amplification or repeaters required. Copper wire, on the other hand, carrying analog signals requiring amplification and noise corrections along the way in much shorter intervals. The result is there is a mix of transmission lines that require special software and equipment such as codecs and modems to convert and move data from one point to another. Codecs and Modems The most common form of analog to digital conversions uses multiplex devices and coder-decoder devices otherwise known as codecs. These programs receive analog signals from sine waves such as audio communications and code them as digital signals. These signals then travel to other locations with codec or modem devices that decode or decompress the data back to analog signals. Digital devices use modems or combinations of codecs and modems to modulate the data signals to analog signals to travel to other modems for demodulation back to digital data.

Review

...In the 1940s, he helped design two of the first stored-program digital electronic computers. He authored reports explaining the functional organization of modern computers for the first time, thereby influencing their construction worldwide (von Neumann, 1945; Burks et al., 1946). In the first of these reports, von Neumann described the computer as analogous to a brain, with an input “organ” (analogous to sensory neurons), a memory, an arithmetical and a logical “organ” (analogous to associative neurons), and an output “organ” (analogous to motor neurons). His experience with computers convinced him that brains and computers, both having to do with the processing of information, should be studied by a new discipline–automata theory. In fact, according to von Neumann, automata theory would cover not only computers and brains, but also any biological or artificial systems that dealt with information and control, including robots and genes. Von Neumann never formulated a full-blown mathematical theory of automata, but he wrote several important exploratory papers (von Neumann, 1951, 1956, 1966). Meanwhile, besides designing hardware, he developed some of the first programs, programming languages,...

...A hybird / digital software package for the solution of chemical kinetic parameter identification problems by ALAN M. CARLSON Electronic Associates, Inc. Princeton, New Jersey INTRODUCTION The modern hybrid computer offers many significant improvements over first generation hybrid systems These improvements include: 1. The increased speed of digital computers en- abling programs to be written in hybrid FORTRAN without drastically limiting hybrid solution rates. 2. The development of analog/hybrid software (e.g., hybrid simulation languages and analog set-up programs). The net result of these improvements has been an increase in the SCope and complexity of hybrid applications and a reduction in the effort required to program and debug hybrid problems. Unfortunately, the dev'elopment of hybrid applications software has not kept pace with recent hybrid improvements. Applications software for purposes of this discussion is defined as an integrated set of digital/hybrid programs capable of solving the majority of frequently occurring problems in a specific applications area. Based on this definition, little or no tangible information is currently available on the practicality of developing hybrid software packages although its benefits are obvious. In mid-1968, EAT's Princeton Computation Center initiated a development project to· determine the feasibility of hybrid applications software....
