A tuned amplifier is generally operated in class B operation.<\/p>\n
In class B operation, the transistor is turned on and off at the peaks of the input signal. This means that the transistor is only amplifying the positive half-cycles of the input signal, and the negative half-cycles are passed through with no amplification. This results in a lower output signal level than class A operation, but it also results in lower distortion.<\/p>\n
Class A operation is characterized by the transistor being turned on throughout the entire input signal cycle. This results in a higher output signal level than class B operation, but it also results in higher distortion.<\/p>\n
Class C operation is characterized by the transistor being turned on for only a small portion of the input signal cycle. This results in the highest output signal level of the three classes, but it also results in the most distortion.<\/p>\n
None of the above is not a valid option.<\/p>\n","protected":false},"excerpt":{"rendered":"
