Abstract
An analog computer program to find and display the Fourier transform of some real, even functions is described. The program has been used as the basis for an undergraduate project and as a lecture demonstration in a wave physics course. The program was run on an EAI TR-20 instructional analog computer and the resulting oscilloscope traces are shown for the Fourier transforms of a rectangular pulse, a Gaussian, a cosine wave, and a delayed narrow pulse.
