In this video, i have explained envelope detector, am detection by following outlines: Envelope detector, am detection 2. An envelope demodulator produces an output signal that follows the envelope of the input am signal exactly. Envelope detection is done to detect the envelope in am output signal. An am signal is demodulated by first mixing the modulated signal y( t ) with another sinusoid of the same carrier frequency. Feed the am signal with 455 khz using function generator observe the message signal output on the cro,and note down amplitude and frequency. Envelope detector is used to detect (demodulate) high level am wave.
