Drawing upon the design and real world user experience of the PLM 20000 touring amplifier, the Ontario, Canada-based audio manufacturer Lab.gruppen, has announced its latest product line, the D series ...

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 ...

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.

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 ...

Class D amplifiers generally use a low-pass filter to attenuate the switching noise in the output waveform while passing the audio signal to the loudspeaker, but many engineers are not familiar with ...

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 ...
