Unit 10 Assignment 2
Signal theory
Digital signalling methods
Digital signal processing (DSP) are procedures which are used to enhance accuracy of data which is transmitted to improve accuracy of data which is transmitted. One example of this would-be radios which use radio waves.
Bits and Bytes bits are tiniest units of data in computers which is known as binary digits. Each bit has a binary value of either 0 or 1, while as multiple bits are known as bytes. Bytes is known for multiple bits which are used in computers which is like bits but contains a bit more data. Bytes ae used to save data and proceed under specific tasks. Packet structures is data which is passed through a network, because of this the bandwidth of communication is better …show more content…
Because of this the receiver and transmitter will sync with one another. The data will be transmitted in packets and used by protocols, one example being Ethernet. asynchronous transmission asynchronous transmission is the opposite of synchronous transmission because data is sent off in spurs, in which this form of transmission is frequently used in communication methods such as telephone lines.
Error detection and correction
Error detection is the usage of software in specific ways to make sure specific data has no errors and is correct. Errors can happen when data is being transmitted because of channel noise. Error correction is the attempt to correct errors which have been detected, it does so by reconstructing the data and making sure there are no errors being transmitted to the receiver. Bandwidth limitation
Bandwidth limitation is set by the internet service provider in which internet service provider sell cheaper prices for lower speeds, and higher prices for higher speeds. Because more customers want a high internet speed, customers are more willing to pay higher prices.
