I. A Brief Description of Other Audio Amplifier Classes (cont?d.)
Class B
? Class B operation is the opposite of Class A. Both
output devices are never allowed to be on at the same
time.
? The output devices have no bias (.6 volts is needed to
bias each device).
? Each output device is on for exactly one half of the time.
Class B designs have high efficiency but poor linearity;
this is due to extreme crossover distortion.
