In today’s world, power amplifiers are used in many devices for a wide variety of applications. In general, an amplifier takes a low power input and regenerates the signal at several watts higher.

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...

In Part 1 of this article, we discussed some of the basic system considerations associated with using audio data converters. We focused on the control method and the basic audio performance metrics ...
