Amplitude Demodulation


To generate an AM signal by implementing its mathematical model. Then you'll set-up an envelope detector using the Rectifier and RC LPF shown in the Fig.1.

Once done, you'll connect the AM signal to the envelope detector's input and compare the demodulated output to the original message and the AM signal's envelope. You'll also observe the effect that an over-modulated AM signal has on the envelope detector's output.
