Q. A binary source generates symbols π β {β1,1} which are transmitted over a noisy channel. The probability of transmitting π = 1 is 0.5. Input to the threshold detector is π
= π + π. The probability density function π_{π}(π) of the noise π is shown below.

If the detection threshold is zero, then the probability of error (correct to two decimal places) isΒ

Ans: 0.12 – 0.14
