THE ANALYTIC SIGNAL REPRESENTAION OF MODULATED WAVEFORMS

Abstract

A general and mathematically convenient formulation of analog- modulated signals which makes use of the analytic signal concept is presented. Known types of modulation are readily identified as special cases. As a result of examining the various cases which the model embraces, a new type of modulation has been discovered--single sideband frequency modulation (SSB FM)-- which can be derived from a conventional phasemodulated signal by an additional amplitude modulation, using the exponential function of the modulating signal's Hilbert transform. The resulting modulated signal will have a onesided spectrum about the carrier frequency, will be compatible with existing FM receivers, and will cause a decrease in signal bandwidth.
