An Electronic Method for Approximating the Frequency Spectra of Transient Functions

Abstract

It is shown that any method for obtaining the spectra (i.e., plots of component amplitude versus frequency) of periodic functions can be used, in a manner described, to determine approximately the spectra of a broad class of transient functions. The problem is thus simplified in that only an instrument for obtaining the spectra of periodic functions need be found. A wave analyzer is then considered as such an instrument.
