A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

Most audiophiles and enthusiasts have grown up with at least a basic understanding of what an amplifier does. It takes a tiny alternating electrical signal that represents the moment-to-moment ...

If you already know about class A, B, and AB, they are all linear amplifiers with constant gain where the audio is fed to the base of a transistor. The latest class D audio amplifier is switch type ...

A class-D puts out a pulse-width modulated (PWM) signal instead of the typical class-AB amplifiers linear signal The PWM signal contains the audio signal and the PWM switching frequency plus harmonics ...

If you're considering your audio-visual setup in any detail, you've almost certainly come across the concept of an amplifier or receiver to handle the sound. But what exactly is the difference between ...
