Consider a discrete memoryless channel and assume that H(x) is the amount of information per symbol at the input of the channel; H(y) is the amount of information per symbol at the output of the channel; H(x|y) is the amount of uncertainty ... (H(x) - H(x|y))] p(x) (D) max H(x|y) p(x) Answer : (D) max H(x|y) p(x)...
