ABSTRACT:
A compound differential circuit detects the highest relative signal of a plurality of input signals. Peak detector circuits including a sensing diode and a capacitor, are employed to produce a control signal. A switch receives the corresponding control signal. One switch is active at a time in response to the highest control signal. An LED connected to the activated switch is illuminated so that a visual indication of the highest input signal is displayed. In another embodiment, a feedback sensor for a graphic equalizer is disclosed.
