Unformatted text preview: Constructing Bode Plots Mark L. McKelvin, Jr. EE 100 Discussion University of California, Berkeley July 27, 2010 What is a Bode plot? Objective: To illustrate how to sketch the Bode plots (magnitude and phase) for a transfer function What is a bode plot? Graph of transfer function that is plotted on a logarithm scale to show frequency response Composed of magnitude and phase plots Why use it? Collapses a wide range of frequencies and gains Transfer Function Components of the transfer function, H(s) where s = j Constant term: K Poles and zeros (real) at origin (where s = 0): |s| Poles and zeros (real) not at the origin: or Complex poles and zeros: or From transfer function to Bode plots (x-axis is ) Magnitude (y-axis) dB = Phase of H(s) (y-axis) degrees = H s = K s z 1 s s p 1 = K z 1 s z 1 1 s p 1 s p 1 1 20 log 10 H s H s 1 s / p 1 1 s / z 1 * Zeros (z): values of s where numerator is 0....
