Conventional AM signals are easily demodulated by an envelope detector.
It consists of a diode and an RC circuit, which is a simple low-pass filter as shown:
  • During the positive half-cycle of the input signal, the diode conducts and the capacitor charges up to the peak value of the input signal.
  • When the input falls below the voltage on the capacitor, the diode becomes reverse-biased and the input disconnects form the output.
  • During this period, the capacitor discharges slowly through resistor R.
  • On the next cycle of the carrier, the diode again conducts when the input signal exceeds the voltage across the capacitor.
The time constant given by RC must be selected to follow the variations in the envelope of the modulated signal.
  • If RC is too large, then the discharge of the capacitor is too slow and the output will not be able to follow the envelope.
  • If RC is too small, then the output of the filter falls very rapidly after each peak and will not follow the envelope closely.
This is explained by the given figure:

So, for the good performance of the envelope detector:
\(\frac{1}{\omega_c}<
