Q. A binary source generates symbols ๐ โ {โ1,1} which are transmitted over a noisy channel. The probability of transmitting ๐ = 1 is 0.5. Input to the threshold detector is ๐ = ๐ + ๐. The probability density function ๐๐(๐) of the noise ๐ is shown below.

If the detection threshold is zero, then the probability of error (correct to two decimal places) is
Ans: 0.12 โ 0.14
