Learn more about Bode plot using these hands-on **Bode diagrams** that we have collected for you! In the following engineering diagrams, the detailed examples of Bode diagrams are illustrated clear pictures. Follow these diagrams to study more about the topic and we’ll start by giving you the simple example diagram below.

A *Bode diagram* is a standard form at 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 recognize the system behavior, or to sketch a plot from what you know about the system behavior. The bode Magnitude plot measures the system Input/Output ratio in special units called decibels. The Bode phase plot measures the phase shift in degrees. More examples of the plot diagram are available in the following images.

Bode diagrams are a very useful way to represent the gain and phase of a system as a function of frequency. This is referred to as the frequency domain behavior of a system. The frequency of the bode plots are plotted against a logarithmic frequency axis. Every tickmark on the frequency axis represents a power of 10 times the previous value. For instance, on a standard Bode plot, the values of the markers go from (0.1, 1, 10, 100, 1000, …) Because each tickmark is a power of 10, they are referred to as a decade. Notice that the “length” of a decade decreases as you move to the right on the graph.
