In Bode diagram (log magnitude plot) the factor in the transfer function gives a line having slope

• -20 dB per octave
• -10 dB per octave
• -6 dB per octave
• -2 dB per octave

Correct Answer: -6 dB per octave

Explanation:

For term the slope is -20 dB/decade or -6 dB/octave because - 20 log 2 = -6 dB.
