What does the envelope detector do?
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 is envelope in envelope detector?
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. ( ωc » ω m ) It consists of two main elements: Diode / rectifier - serves to enhance one half of the received signal over the other.
Is envelope detector and diode detector same?
Envelope Detector
Here, the diode is the main detecting element. Hence, the envelope detector is also called as the diode detector.
Which diode is used in envelope detector?
The AM diode detector is an envelope detector – it provides an output of the envelope of the signal.
