Abstract
A technique is provided for identifying waveform period or specific events during a waveform period. A periodic waveform is an input signal for a comparator, voltage divider and a balanced load. The circuitry produces a square waveform that has the same period as the input waveform, but is phase shifted based upon time required for the input waveform to cross positive and negative offsets from a zero axis. The resulting timing signals may be used for analysis of the input waveform, such as for RMS calculations based upon sampling of the input waveform.
