Abstract
A synthesized sinusoid generator for delivering to an acoustic driver high ower of a discrete spectral component from a spectrum including the discrete spectral component and its harmonics. The generator uses a plurality of unity gain switching amplifiers and involves summing various stages thereof at full power. This is accomplished by switching on and off various unity gain switching amplifiers as a function of time of the fundamental, thus necessitating only generation of the fundamental frequency and a delay network to switch on and off the designated unity gain switching amplifiers.
