What is one of the great advantages of the diode envelope detector?
The main advantage of this form of AM Demodulator is that it is very simple and cheap! Just one diode, one capacitor, and one resistor. That's why it is used so often. However, it does suffer from some practical problems.
What is the purpose of an envelope detector?
An envelope detector can be used to demodulate a previously modulated signal by removing all high frequency components of the signal. The capacitor and resistor form a low-pass filter to filter out the carrier frequency.
What are the advantages of practical diode detector?
(i) It can handle large input signals. (ii) It is highly efficient. (iii) It produces dc voltage for automatic gain control. (iv) It rectifies with minimum distortion.
