A television channel with bandwidth 5 MHz is normalized to peak voltages +1 V, and the average power is 30 mW. The signal must be sampled at least 25% above the Nyquist rate. The signal is uniformly quantized and the signal to quantization noise ratio is required to be at least 30 dB. Suppose that we multiplex 15 such channels and the multiplexed signal is transmitted using 32-ary PAM signaling.
(c) Compute the power needed to transmit the same signal at the same rate using binary polar signaling while achieving the same noise immunity. What is the required bandwidth in this case?
