Question

A communication channel has transfer function

 H(f)= 200/(400+j2πf)

The channel noise is AWGN with spectrum Sn (f ) = 10^(-4). The transmitter power constraint is P = 10

(a) Find the optimum input signal PSD under the power constraint.

(b) Find the maximum channel capacity under the power constrain
