Good day Guys,
I am working on an AM Modulator and Demodulator circuit using the diode method. My modulation signal is a 10kHz Square Wave and I have a carrier frequency of 850 kHz. My modulation works just fine, according to my general knowledge, however, my demodulator is currently outputting a very weird looking wave, it resembles a square wave but is not close enough to know it was one, at first sight, my question is how can I improve the demodulation?
I have attached a screen shot of my circuit and the various outputs(Input Signal - Blue, Modulated signal - Red, Demodulated Signal - Green) below,
Note 1: I am using LtSpice.
Note 2: This circuit is just for me to learn how the modulation and demodulation works, and thus it has implemented ideal diodes and none practical component values.
