Simple Envelope Detection

Granted, this is not Amplitude Modulation per se, but the same rules still apply. The amplitude of the audio signal is superimposed on the carrier, which can be easily demodulated using a simple envelope detector. I've added a little extra bonus demodulation using a notch filter. The last one will usually not work with AM because a detector needs a nonlinear component like a diode to separate the signals, but as i said this is not AM.
