9-A binary data source has P(OT) = 3/8, due to interference of channel, then P(OR/1T) = 1/16 and P(1R/0T) = 3/4. Calculate the noise and losses entropies and compare with source entropy.

Consider a telephone line initially noiseless channel having bandwidth and signal level determined by the network engineer. Calculate maximum data rate. After certain distance the channel becomes extremely noisy, so that the noise is strong which faints the signal .Calculate the capacity of the channel.
