A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...

Embedded electronics has continued to ramp up across the automotive landscape, taking on more substantial roles in many applications. One example is the presence of multiple class-D audio amplifiers ...

A new book authored by Robert N. Buono delves deeply into Class-D amplifiers, a crucial technology in audio designs. Buono has more than four decades of experience in analog and power electronic ...

In order to perform this harmonic reduction, a pure sine wave must first be applied to the Class-D amplifier system. Using the ternary modulated bitstreams described earlier, two pulse density ...

Previously, we wrote about the Louder Raspberry Pi, an open-source media center that integrates the Louder Raspberry Hat ...

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 existence.
