My understanding of demodulators is pretty basic, so I would like some help on this. I have a carrier wave at 10MHz at 0.1 Vpeak and am trying to demodulate it (eventually it will be buried in noise). I am simulating a circuit on NI Multisim, but when I hook up the output to the oscilloscope something that looks completely saturated comes up. Here are some details:
- My phase shift, quadrature and ePAD pins are all grounded
- The local oscillator is at 12MHz and 0.1 Vpeak
Could anyone help me achieve a better simulation?
