Question: Explain the detection of am signal using envelope detector?

The envelope detector is a simple circuit used to detect amplitude-modulated (AM) signals. It works by extracting the envelope or variations in the amplitude of the modulated signal. The AM signal is first rectified, converting the negative half of the signal into positive values. Then, a low-pass filter is used to smooth out the rectified signal, eliminating the high-frequency carrier and leaving behind the original modulating signal. This resulting waveform represents the envelope of the AM signal, which can be further processed or demodulated to recover the original audio or information embedded in the AM signal. The envelope detector is a fundamental component in AM receivers, allowing the extraction of the modulating signal from the carrier wave.
