A Class D amplifier works in very much the same way as a PWM power supply (we will show the analogy later). Let’s start with an assumption that the input signal is a standard audio line level signal. This audio line level signal is sinusoidal with a frequency ranging from 20Hz to 20kHz typically.

How do Class D amplifiers work? A Class D amp works by taking the analog input signal and creating a PWM (pulse width modulation) replica of it-essentially a train of pulses, which correspond to the amplitude and frequency of the input signal. In its most basic form, a comparator circuit is used to match the input signal with the PWM signal.

Class D amplifiers function by taking the analog input signal and they replicate a pulse with modulation, it basically looks like a row of pulses, which then correlate with frequency and amplitude of the aforementioned input signal. In its original state you use a comparator circuit so you could match the input signal with the pwm signal.
How a Class D "Digital" Amplifier Works - Audioholics

Basically, a digital (Class D) amplifier takes an incoming analog signal and converts it into a digital representation comprised of pulse widths. Although there are a number of different design variations, Class D amplifiers are essentially switching amplifiers or Pulse Width Modulator (PWM) designs.

A class-d amplifier is an electronic amplifier also known as a power switching amplifier. where the output transistor stage operates as electronic switches, and there are not much linear gain as other amplifiers do. A class D amp starts work by taking an incoming analogue input signal and generating PWM or PDM.

Because the output transistors switch the output to either V DD or ground, the resulting output of a Class D amplifier is a high-frequency square wave. The switching frequency (f SW) for most Class D amplifiers is typically between 250kHz to 1.5MHz. The output square wave is pulse-width modulated by the input audio signal.

What is a Class D Amplifier? Class D is defined as analog, even though some people consider it digital. In fact, class D is something called “post rhythm modulation.” It basically means it works in a very efficient manner: an input signal comes in and it is compared to a rising amp. Now, you may be thinking what is a rising amp?
