The almost universal choice in semiconductor power amplifiers is for a unity gain output stage, and specifically a voltage follower. Output stages with gain are not unknown, 1 but they are not common.

There are two salient facts about Class A amplifiers: they are inefficient; they give the best possible distortion performance. The quiescent dissipation of the classic Class A amplifier is equal to ...

Distortion. Present in every electro-mechanical-acoustical transducer ever built, yet infrequently does one find information (let alone useful information) that describe the type and degree of ...

Intermodulation distortion is one of the most interesting signal analyzer measurements. Often abbreviated IMD, it is an important metric of linearity for a wide range of RF and microwave components.

An audio distortion analyzer is a specialist piece of analogue test equipment that usually costs a lot of money and can be hard to track down on the second hand market. Finding one is a moment of luck ...

Distortion comes in a huge range of slightly different forms, from subtle analogue warmth to extreme metal fuzz, mild digital imprecision to eardrum-bursting clipping. But what is distortion, what's ...
