a) Digital communication in our time today has made technology easier to live with. Discuss the compression techniques which are proposed for still images? b) Under the coding techniques available in communication system, elaborate on the one which seeks to minimize the data which reduces the size. c) To ensure a transmission free loss in a communication network, some considerations were made to determine the channel capacity. An AWGN channel with 4.0112-kHz bandwidth with a noise power spectral density of W/Hz. The signal power necessary at the receiver is 0.111 mW. Find the channel capacity of this network that will bring about the loss free transmission.
