PULSE TESTING VIA THE FAST FOURIER TRANSFORM.

Abstract

Subroutine REFFT accomplishes a fast, accurate transformation of time domain pulse response data to frequency response data using the real valued fast Fourier transform. The subroutine is written in Fortran IV and has been compiled and tested on a 7040, A S/360 Model 50, and a S/360 Model 65. Given time domain input and output pulse data the subroutine will calculate and print magnitudes, phase angles and associated frequencies. (Author)
