Question
A simple binary communication channel carries messages by using two signals 0 and 1. It was
assumed that for a given binary channel, 40% of the time a 1 is transmitted; the probability that a
transmitted 0 is corectly received is 0.90; the probability that lis correctly received 0.95. This
information is illustrated in Figure 1 where
A= event that 1 is transmitted.
A= event that 0 is transmitted.
B = event that 1 is received.
B = event that 0 is received.
