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 ...

As Axiom’s chief R&D engineer Tom Cumberland describes it, a digital amplifier is a “power DAC”, and of course a DAC (Digital-to-Analog Converter) is the basis of all digitally recorded media, whether ...

With the proliferation of digital sources for audio, opportunities exist to amplify the signal entirely in the digital domain, right up to the loudspeaker. The performance of an open loop digital ...

The Class D amplifier has some added challenges. Real world transistor switching characteristics require that some degree of dead-time is present in each modulation cycle to control the ...
