I have implemented an ASK modulator and demodulator pair. The modulator works fine, but the demodulator is giving a vague output. Below is the image of the whole circuit and the simulation output.
In the below output, blue is the carrier of 27 MHz, red is the digital wave of 150 KHz, green is the ASK output and yellow is the de modulator output.
I am not much of an electronics guy, so not good in tuning the circuit. Please help me achieve the desired output so that the yellow wave resembles the red digital wave.
EDIT 1 -
After trying many combinations of R11 and C2 values, finally i got one that is sending considerable voltage into demodulator. The output is still a straight line but its non zero this time.
