I know the inverse fourier transform is simple but I am concerned with a general procedure or process. I am most interested in the cases where $a,b=±∞$ although a simple inverse for $\int^{a}_{b} f(x) dx$ is also something I am curious about (as far as this part of the question is concerned, if the...Nov 01, 2017 · Linear Systems and Signals, Third Edition, has been refined and streamlined to deliver unparalleled coverage and clarity.
