Consider a binary digital communication system with equally likely $$0’s$$ and $$1’s$$.
When binary $$0$$ is transmitted the voltage at the detector input can lie between
the levels $$-0.25V$$ and $$+0.25V$$ with equal probability when binary $$1$$ is
transmitted, the voltage at the detector can have any value between $$0$$and $$1 V$$
with equal probability. If the detector has a threshold of $$2.0V$$ (i.e., if the received
signal is greater than $$0.2 V$$, the bit is taken as $$1$$), the average bit error
probability is
