In an RC coupled amplifier, the voltage gain over mid-frequency range_____________?
Correct answer: B. Is constant
- A. Changes abruptly with frequency
- B. Is constant
- C. Changes uniformly with frequency
- D. None of the above
Explanation
In the mid-frequency range, the coupling and bypass capacitors act nearly as short circuits while transistor parameters remain fairly stable, so the voltage gain is approximately constant. Gain changes mainly at low and high frequencies.
