A continuous-time sigA continuous-time signal is sampled and then transmitted as a PCM signal. The random variable at the input of the decision device in the receiver has a variance of 0.01 volts2 (a) Assuming the use of polar NRZ signaling, determine the pulse amplitude that must be transmitted for the average error rate not […]
