TL;DR: A mathematical model is presented, characterizing the pulse ratio modulation technique in terms of input output relationships, and a procedure, based on the use of projection operators in vector spaces, is presented to analyse the asymptotic stability in the large.

TL;DR: In this paper, the modulator output spectrum is given in terms of the single harmonic components, and the method of subharmonic control is thoroughly examined and a modified technique is pointed out, with a spectrum characterized only by odd harmonics of the modulating frequency.
