Unformatted text preview: • At secondorder break points, sketch in the resonant peak (or valley) according to Figure 9.11(a) using the relation G(j ϖ )(db)=–20log(2 ξ ) at denominator (or G(j )(db)=20log(2 ) at numerator) break points. 6. Sketch in the approximate phase curve by changing the phase by 90 ± or 180 ± at each break point in ascending order: • For each firstorder term in the numerator, the change of phase is 90 + ; • For each firstorder term in the denominator, the change of phase is 90; • For each secondorder term in the numerator, the change of phase is 180 + ; • For each secondorder term in the denominator, the change of phase is 180....
