Bode plot of complex pole
WebThe Bode plot of the transfer function H (s) is obtained by plotting the logarithm of the magnitude of H (s) (in decibels) against the logarithm of frequency and the phase angle of H (s) against the logarithm of frequency. where X (s) is the Laplace transform of the input signal x (t), and Y (s) is the Laplace transform of the output signal y (t). WebMar 5, 2024 · The Bode magnitude plot (Figure 6.1.2) has an initial slope of − 20 dB per decade that gradually changes to − 40 dB per decade at high frequencies. The phase plot shows a variation from − 90 ∘ to − 180 ∘ with a phase of − 135 ∘ at the corner frequency.
