This paper addresses the problem of generating constant-envelope wideband (CEW) signals, for which applications are emerging both in telecommunications (as information carriers) and in digital/power electronics (to aid the synthesis of timing signals which favor electromagnetic compliance). A flexible generation technique consists in driving a frequency modulation (FM) modulator with random or chaotic sequences. Mathematical tools for predicting some spectral properties of random-FM and chaotic-FM CEW signals are herein introduced by commenting on recent results and presenting novel ones in a coherent framework.
