ABSTRACT:
Variable frequency sine waves are converted to constant amplitude cosine waves using the relationship cos .omega.t = .sqroot.1-sin.sup.2 .omega.t. The converter has an almost instantaneous response characteristic and is suitable for a wide frequency range. An application is cosine timing waves for phase controlled converters and cycloconverters.
