Exam 33: Power Amplifiers

The characteristics of a class B amplifier using a single transistor include medium efficiency and severe distortion.

The maximum possible efficiency of an RC coupled class A amplifier cannot exceed 8.33% no matter what is done.

Which class amplifier has characteristics that include very high efficiency and severe distortion of the input signal?

A class A amplifier cannot be used as a linear amplifier.

With no ac input signal applied to the amplifier, the transistor has a power dissipation equal to the voltage, collector to emitter at quiescence times the collector current at quiescence.

The signal amplitude of any class A amplifier at the input should not be large enough to drive the amplifier into either cutoff or saturation.

______________ distortion results in a class B push-pull amplifier when the transistors are biased at cutoff.
