Abstract
An envelope detector for detecting the envelope of an input signal. The envelope detector includes an inverter for inverting the input signal and two offsetting circuits for offsetting the input signal and the inverted input signal so as to align the peaks of the signals with zero volts. The two offset signals are then summed, which results in a signal proportional to the inverted envelope of the input signal.
