Abstract
A simple system which employs an ultrasonic strip line as a linear dispersive delay filter has been implemented for demonstrating Fourier transform relationship in real time. Fourier transforms of signals having rectangular, triangular and trapezoidal waveforms have been successfully obtained. Results are in good agreement with theoretical plots.
