Abstract
Tracking percent overload signal as an indicator of output signal magnitude is achieved by measuring the percent of time the envelope of a varying modulated signal is above a predetermined programmable threshold. The technique is implemented by a level detector including an envelope detector along with circuitry for detecting when the envelope has exceeded the programmable threshold. The output of the level detector is sampled and fed to a counter which provides a digital output which indicates the percentage of time the envelope exceeds the set threshold.
