The Class D audio amplifier - Basics (1/3)
#164 In this video I continue looking at the various amplifier classes, by starting working on the switching amplifiers. First up - the class D audio amplifier. I look at why a switching amplifier would be better than a linear one, and then I start looking at how the class D amplifier turns linear signals into square waves. So I mainly look at how you can get binary and ternary PWM modulation.
