Amplifier And Oscillators

Subject : engineering
Instructions:
  • Answer 9 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • 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. A device that provides gain without much change in the original wavelength.






2. It is designed to amplify either voltages or power.






3. Class of amplifiers where 100% of the input signal is used. And it changes the phase of the signal but not the shape.






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.






5. Class of amplifiers where only 50% of the input signal is used and amplifies only half of the signal. The output signal is distorted.






6. It is used as a measurement of audio signals strength and gain.






7. 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.






8. It is the ratio of the output signal to input signal of an active component.






9. Class of amplifiers where less than 50% of the input signal is used. Efficiency is high - but so is the distortion.
