A traditional PWM switching amp design uses a fixed switching frequency and varies the pulse width based solely on the audio input signal to the pulse modulator.

Power supply sag with signal causes distortion at all power levels with these designs, even well below clipping.

A traditional PWM switching amp design uses a fixed switching frequency and varies the pulse width based solely on the audio input signal to the pulse modulator.

Power supply sag with signal causes distortion at all power levels with these designs, even well below clipping.
