Question

How can the gain roll off represented in dB/octave?

(a) 12 dB/octave

(b) 6 dB/octave

(c) 10 dB/octave

(d) 8 dB/octave

This question was addressed to me in an online quiz.

My doubt is from Open-Loop Voltage Gain as a Function of Frequency topic in section Practical Limitations of Op Amp Circuits of Linear Integrated Circuits

Answer 1

The accurate option is (b) 6 dB/octave

Dive into clarity with: Octave represents a two fold increase in frequency. Therefore, 20 gain roll off at the rate 20 dB/decade is equivalent to 6 dB/octave.
