Envelope Detector Schematic. An envelope detector is an electronic circuit that takes a high frequency signal as input and provides an output which is the envelope of the original signal. An envelope detector is sometimes called as a peak detector.

On a positive half cycle of the input signal the diode is forward biased and the capacitor c charges up rapidly to the peak value of the input signal. An envelope detector is an electronic circuit that takes a relatively high frequency amplitude modulated signal as input and provides an output which is the demodulated envelope of the original signal. An envelope detector is sometimes called as a peak detector.
On a positive half cycle of the input signal the diode is forward biased and the capacitor c charges up rapidly to the peak value of the input signal.
On a positive half cycle of the input signal the diode is forward biased and the capacitor c charges up rapidly to the peak value of the input signal. The capacitor in the circuit stores up charge on the rising edge and releases it slowly through the resistor when the signal falls. On a positive half cycle of the input signal the diode is forward biased and the capacitor c charges up rapidly to the peak value of the input signal. An envelope detector is sometimes called as a peak detector.
