AM, or amplitude modulation, was the earliest way of sending voice over radio waves. That makes sense because it is easy to modulate a signal and easy to demodulate it, as well. A carbon microphone… ...

The second trace, function F1, uses the demodulate math function to compute the amplitude envelope of the RF pulse. This shows amplitude spikes where the Barker codes cause a change in phase.

Due to the time-synchronous nature of the track function, you can use it to demodulate signals like this PWM waveform. By tracking the parameter frequency, you can use it to also demodulate a ...
