[Part 1 discussed the methodology behind Class-D amplifiers and the ternary modulation scheme.] Results In order to perform this harmonic reduction, a pure sine wave must first be applied to the Class ...

Class D amps are simple – just take an input, and use that to modulate a square wave with PWM. Send this PWM signal to a MOSFET or something, and you have the simplest class D amp in existenc… ...

A block diagram of the Class-D amplifier is shown in Figure 1. The techniques discussed in this paper describe how a single-frequency, sine wave signal was generated through a Class-D amplifier with ...
