PLEASE do not just copy and paste the solution manual answer as I ready have the solution. I want a full explanation of this problem. Be as detailed as you can especially in part 5. Thanks

4.10 The noise voltage in an electric circuit can be modeled as a Gaussian random variable with mean equal to zero and variance equal to 10-8. 3. This noise passes through a half-wave rectifier with characteristics g(x)-(0, x>0 x, x > 0 0, xs0 Find the PDF of the rectified noise by first finding its CDF. 4. Find the expected value of the rectified noise in the previous part. 5. Now assume that the noise passes through a full-wave rectifier defined by g (x)-|xl. Find the density function of the rectified noise in this case. What is the expected value of the output noise in this case? 4.10 The noise voltage in an electric circuit can be modeled as a Gaussian random variable with mean equal to zero and variance equal to 10-8. 3.
