Problem 3. We are transmitting our 12/4 APSK signal with outer ring voltage 10 Volts and inner ring voltage = 2 Volts through a channel where the noise power in the channel equivalent noise bandwidth is 0.2 Watts a) What is the SNR, in dB, of the outer ring symbols? b) What is the SNR, in dB, of the inner ring symbols? c) What is the average SNR, in dB across the constellation if all symbols are equally likely? (Remember to average in linear and then convert to dB)

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
