Abstract
A new power and energy-to-frequency converter is described. Its operation is based on two closed-loop mean-square value-to-frequency converters of new conception in which a direct digital feedback is used. Error analysis is carried out and performance data of an experimental circuit using indirectly heated thermistors are given. The instrument is suitable for digital power measurement for both dc and ac wide-band signals disregarding its waveform.Keywords
