Sample text

Current-dumping amplifiers can be regarded as combining Class-A (the correcting amplifier) with Class-C (the current-dumping devices); however it is hard to visualise how an audio amplifier using devices in Class-C only could be built. Class-D These amplifiers continuously switch the output from one rail to the other at a supersonic frequency, controlling the mark/space ratio to give an average representing the instantaneous level of the audio signal; this is alternatively called Pulse Width Modulation (PWM).

Proposed standards for the maintenance of absolute phase have just begun to appear [31], and the implication for amplifier designers is clear; whether absolute phase really matters or not, it is simple to maintain phase in a power amplifier (compare a complex mixing console, where correct phase is vital, and there are hundreds of inputs and outputs, all of which must be in phase in every possible configuration of every control) and so it should be done. In fact, it probably already has been done, even if the designer hasn’t given absolute phase a thought, because almost all amplifiers use series negative feedback, and this must be non-inverting.
