In obtaining the frequency response curve of an amplifier, the______________?
Correct answer: D. Generator output level is held constantDiscover Home Audio
- A. Amplifier level output is kept constant
- B. Amplifier frequency is held constant
- C. Generator frequency is held constant
- D. Generator output level is held constantDiscover Home Audio
Explanation
To plot an amplifier’s frequency response, the generator output level is kept constant while its frequency is varied and the amplifier output is measured. This makes changes in output due to frequency response rather than changes in input amplitude.
