ABSTRACT:
The frequency range and accuracy of a commercially available RMS converter is improved by providing an improved rectifier ahead of the converter's internal rectifier. The improved rectifier switches between the input signal and an inverted version of the input signal in response to a high speed comparator. The improved rectifier can also incorporate range selecting circuitry.
