Bode Diagrams of Transfer Functions and Impedances ECEN 2260 Supplementary Notes R. W. Erickson In the design of a signal processing network, control system, or other analog system, it is usually necessary to work with frequency-dependent transfer functions and impedances, and to construct Bode diagrams. The Bode diagram is a log-log plot of the Bode Plot Example of First-Order System using Matlab. In this article, Bode Plot of Simple Phase-Lag Network (First Order System) is obtained using Matlab. In order to draw Bode Plot, we need transfer function from which we deduce the equations for Magnitude and Phase.

Bode Plots Page 1 BODE PLOTS A Bode plot is a standard format for plotting frequency response of LTI systems. Becoming familiar with this format is useful because: 1. It is a standard format, so using that format facilitates communication between engineers. 2. Many common system behaviors produce simple shapes (e.g. straight lines) on a Bode plot, so it is easy to either look at a plot and 3.
