Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. It is used as a measurement of audio signals strength and gain.
Class B
Decibel
Function Response
Class AB
2. It is an amplifier circuit that uses positive feedback to provide output waveforms without an input signal. Converts DC signal to an AC output signal.
Oscillator
Class A
Function Response
Gain
3. Class of amplifiers where 100% of the input signal is used. And it changes the phase of the signal but not the shape.
Decibel
Class AB
Class A
Amplifier
4. Class of amplifiers where it operates during 51% to 99% of the input signal. Better power efficiency than class A and less distortion than class B.
Class C
Class AB
Gain
Oscillator
5. Class of amplifiers where less than 50% of the input signal is used. Efficiency is high - but so is the distortion.
Decibel
Gain
Class AB
Class C
6. A device that provides gain without much change in the original wavelength.
Class B
Decibel
Amplifier
Class C
7. It is designed to amplify either voltages or power.
Class B
Function Response
Class A
Oscillator
8. It is the ratio of the output signal to input signal of an active component.
Gain
Class B
Class A
Amplifier
9. Class of amplifiers where only 50% of the input signal is used and amplifies only half of the signal. The output signal is distorted.
Gain
Class B
Class AB
Amplifier
