Analog ElectronicsFrequency Response

At a single first-order high-frequency pole, the asymptotic gain slope beyond the pole is approximately?

  • A-6 dB/octave
  • B-12 dB/octave
  • C+6 dB/octave
  • D0 dB/octave
Report an error
Correct Answer: A. -6 dB/octave
Explanation: A single pole contributes approximately -20 dB/decade, equivalent to about -6 dB/octave.
