Question A-002-006-003

For what portion of a cycle does a Class AB amplifier operate?

Correct Answer

More than 180 degrees but less than 360 degrees

Class AB amplifiers are biased so that current flows for more than half a cycle (180°) but less than a full cycle (360°), offering a compromise between Class A linearity and Class B efficiency.
