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
Oscillator
Decibel
Class AB
2. A device that provides gain without much change in the original wavelength.
Amplifier
Decibel
Class AB
Class B
3. 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.
Class C
Amplifier
Oscillator
Class B
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.
Function Response
Class A
Class AB
Class C
5. It is the ratio of the output signal to input signal of an active component.
Oscillator
Gain
Function Response
Decibel
6. Class of amplifiers where 100% of the input signal is used. And it changes the phase of the signal but not the shape.
Class AB
Class A
Oscillator
Amplifier
7. Class of amplifiers where less than 50% of the input signal is used. Efficiency is high - but so is the distortion.
Class AB
Oscillator
Class C
Class A
8. It is designed to amplify either voltages or power.
Class C
Class B
Function Response
Oscillator
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.
Class B
Class C
Amplifier
Class A
