So now instead of just going through a lowpass filter, it goes through a lowpass filter, then is sampled, and then is run into an analog-to-digital converter that assigns a numerical value to the amplitude of the signal at the instant it is sampled. The pre-compression operates much more efficiently than the on-the-fly compression of V.
This is the Modfm Rate; any signal sampled at a rate equal to twice its highest frequency component can 56, completely reconstructed.
