Problem 6.1 OPP Prove that a magnitude slope of -1 in a Bode plot corresponds to -20 db per decade or -6 db per octave. Step-by-step solution step 1 of 1 Step 1 of 1 The m ^ i tu d e of G(jo)) in dB is obtained by multiplying the logarithm to the base 10 of |G (-j0)| by 20 |G(jcD)|dB=2Caog|G(j(!))| If |G ( - j . . ) |= t 201og]QK=201ogK,ffi |G (jco) I dB=201 ogu,E-201ogjp(D Which has solpe of -20dB per decade Also if = 2c0i then it is called as Octave since -201og2 = -6dB, the slope could also be expressed as-6dB/octave
