How do you calculate the envelope of the AM signal?

e(t) = Ac|1 + kam(t)| is called the envelope of the AM signal.

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.
