Modulator and demodulator PAM

2050

1d 00:31:56

Green wave -: input signal
Blue wave -: modulated signal
Orange wave :- demodulated wave
It looks like AM butits high frequency PAM . 

Change input to square wave -10V to +10V wave and see the slew rate effect on demodulated wave due to opamp caused in demodulator which gives the real squae wave or prctical square wave passed through opamp .

Good work. Both modulation and demodulation and correct. Keep it up
