The output voltage X from the receiver in a particular binary digital communication system, when a binary zero is being received, is gaussian (noise only) as defined by aₓ= 0 and σₓ= 0.3. When a binary one is being received it is also gaussian (signal- plus-noise now), but as defined by aₓ= 0.9 and σₓ= 0.3. The receiver's decision logic specifies that at the end of a binary (bit) interval, if x > 0.45 a binary one is being received. If x < 0.45 a binary zero is decided. If it is given that a binary zero is truly being received, find the probabilities that a binary one (mistake) will be decided.
