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. 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
Gain
Amplifier
Class C
2. It is designed to amplify either voltages or power.
Function Response
Oscillator
Gain
Class AB
3. It is used as a measurement of audio signals strength and gain.
Function Response
Amplifier
Gain
Decibel
4. A device that provides gain without much change in the original wavelength.
Decibel
Amplifier
Class A
Class C
5. Class of amplifiers where less than 50% of the input signal is used. Efficiency is high - but so is the distortion.
Class C
Gain
Class A
Amplifier
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 B
Oscillator
Class A
Decibel
7. It is the ratio of the output signal to input signal of an active component.
Amplifier
Class B
Class AB
Gain
8. 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.
Decibel
Class C
Amplifier
Oscillator
9. 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.
