A logic 0 is transmitted at a nominal level of 0 V and a logic 1 is transmitted at a nominal level of 1.2 V. Each logic level has equal probability of being transmitted. If a 100-mV RMS Gaussian noise signal is assumed to be present at the receiver, what is the probability of making an single trial bit error if the detector threshold is set at 0.6 V. Repeat for a detector threshold of 0.75 V.
