This method relates constant continuous functions to 2 pi scaled Dirac deltas, and turns modulation of two signals in time to a 2 pi scaled convolution.
The Wiener-Khinchin theorem relates it to the autocorrelation function and the modulation theorem allows for the simplification of it when a shift is induced by a cosine term. This method relates constant continuous functions to 2 pi scaled Dirac deltas, and turns modulation of two signals in time to a 2 pi scaled convolution. FTP name this representational methodology relating time and frequency domain signals named after a French mathematician.
