A Class D audio amplifier works by converting the input audio signal into a series of high-frequency pulse-width modulated (PWM) signals. These pulses drive the output transistors, which switch on and off rapidly to produce a corresponding amplified signal. The amplified PWM signal is then filtered through a low-pass filter to remove the high-frequency components, leaving behind the amplified audio signal for the speakers.
