Question 1

Classes of amplifiers

Answer 1

A
B
C
AB
Push Pull
Thryaton
Control Circuits

Question 2

Class A amplifier

Answer 2

good fidelity, low efficiency
The best amplifier to use for the “truest” amplification
only about 20% of power consumed is used to amplify, the other 80 is wasted
used for radio, radar and sound systems

Question 3

Class B amplifier

Answer 3

twice as efficient as class a
only amplifies half the waveform (positive or negative)
used for audio amplification that requires high outputs

Question 4

Class C amplifier

Answer 4

operates on less that 50% of the waveform
is the most efficient, however is the worst fidelity
used as radio frequency amplifiers
