The process of seperating one stage of an amplifier from another. Decoupling prevents oscillations and other noises that may occur due to unwanted feedback through the power supply connections. It ...

Class A

Consumer electronics; Amplifier

An amplifier operating with the grid bias adjusted so plate current flows for the entire 360 degrees of the input waveform, by biassing the tube halfway between cutoff and saturation, in the most ...

Class A1

Consumer electronics; Amplifier

Class A operation where grid current does not flow for any portion of the input cycle.

Class A2

Consumer electronics; Amplifier

Class A operation where grid current flows for some portion of the input cycle.

Class AB

Consumer electronics; Amplifier

An amplifier operating with the grid bias adjusted so plate current flows for greater than 180 degrees, but less than 360 degrees of the input waveform, by biassing the tube above cutoff, but below ...
