A class-D puts out a pulse-width modulated (PWM) signal instead of the linear signal that is typical in class-AB amplifiers. The PWM signal contains the audio signal and the PWM switching frequency ...

The most common audio power amplifier operates in the Class-AB mode. It provides the greatest amount of output power with the least amount of distortion. The downside is that it consumes quite a bit ...

The efficiency and size advantages of Class D audio amplification in battery- powered devices are well known. These advantages are now extended to amplifiers up to 500W, made possible by solidstate ...

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...

Apogee Technology has complained about some of Texas Instruments Inc.'s Class D claims. In March, TI called itself the first to introduce a single-chip Class D amplifier in the 125-watt/channel range.
