# A binary PCM wave uses unipolar NRZ signaling to transmit

A binary PCM wave uses unipolar NRZ signaling to transmit symbols 1 and 0; symbol 1 is represented by a rectangular pulse of amplitude A and duration Tb. The channel noise is modeled as additive, white and Gaussian, with zero means and power spectral density N0/2. Assuming that symbols 1 and 0 occur with equal probability, find an expression for the average probability of error at the receiver output, using a matched filter as described in Section 4.3.
