Signals with flattened extrema in balance power analysis of HFHPTA: Theory and applications

Abstract

In this paper a complete and self-contained account of composite periodic signals with two and three harmonics which possess flattened extrema at the zero point, including their application in the balance power analysis of HF high-power tuned amplifier (HFHPTA), is presented. It is shown that signals obtained in the balance power analysis of HFHPTA and their derivatives can extremely accurately be approximated with the corresponding signals with flattened extrema at the point θ = 0. Two theorems presented in the paper give canonical representations of such signals.
