comment Stuck on 'differentiating the integral from above' for computing of a PDF
Wait... is it because $\frac{d}{dz}F_Y(-z) = \frac{d}{dz}[F_Y(\infty) - F_Y(z)] = \frac{d}{dz}[1 - F_Y(z)] = -f_Y(z)$ ?...

Thanks, but can you please explain how $\frac{d}{dz}F_Y(-z) = -f_Y(z)$?....

comment What is the intuition behind a function being 'weakly differentiable'?
Christopher, by sign(x[n]) I just mean the non-linear operation of taking the sign of that particular number in the vector. For example, in my case, if my x[n] = [-2 1 4 -18 4 -3], then sign(x[n]) = [-1 1 1 -1 1 -1]
