Class D amplifier - What is it?
Class-D amplifiers work by generating a train of rectangular pulses of fixed amplitude
but varying width and separation. This modulation represents the amplitude variations of the
analog audio input signal. The output of the modulator is then used to turn the output transistors
on and off alternately. Since the transistors are either fully on or fully off, they dissipate
very little power. A simple low-pass filter consisting of an inductor and a capacitor
provides a path for the low frequencies of the audio signal, leaving the high-frequency
pulses behind.
