A fundamental difference between class A and class D amplification


Is it the following?


Imagine a small toy boat in a bathtubs. Class A (electrons flowing all the time through the amplifier) means the waveform passes naturally from all values of displacement. The little ship moves by a hand, a water wave etc.


Is class D taking a hammer and hitting the little boat at periodic intervals?  The boat does not move so abruptly as it has mass, inertia. This is mechanical low pass filtering.
