The output voltage X from the reciever in a particular binary digital communcations system, when a binary 0 is being received, is gaussian (noise only) as defined by µx = 0 and σX = 0.3. When a binary 1 is recieved it is also gaussian (signal plus noise now), but as defined by µx = 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 receieved, find the probabilities of correct decision or mistake will be decided,and (b) a binary zero is decided (correct decision)
