A simple configuration of first-quadrant analog multiplier/divider has been applied to an R. M. S. -D. C. converter. The output voltage of the R. M. S. -D. C. converter is in good proportion to the true R. M. S. value for a D. C., a sine wave, a square wave, a triangular wave and pulse trains. The error is within 1% of full scale.
