ABSTRACT:
A relatively simple, inexpensive, effective circuit for detecting overdriving of a radio frequency amplifier by an amplitude modulated signal. The input and output signals of the amplifier are coupled to peak detectors. A light emitting diode which provides a visual indication of the overdrive condition is coupled between the peak detectors.
