MCQ Practice Question
Analog ElectronicsFrequency Response

If the lower and upper cutoff frequencies of an amplifier are 100 Hz and 100 kHz respectively, its bandwidth is approximately?

  • A99.9 Hz
  • B9.99 kHz
  • C99.9 kHz
  • D100.1 kHz
Report an error
Correct Answer: C. 99.9 kHz
Explanation: Bandwidth = fH - fL = 100000 - 100 = 99900 Hz = 99.9 kHz.
Reference: Standard analog electronics: frequency response
