What Are Bode Plots? @MATLAB

Uploaded August 2025 | Updated September 2026, 2 weeks ago

Learn the principal characteristics of a Bode plot in this MATLAB® Tech Talk by Carlos Osorio. This video explains how a Bode plot describes the frequency response of a linear time-invariant system and the plot’s primary characteristics, such as the DC gain, roll-off rate, natural frequency, crossover frequency, and bandwidth frequency. You will also learn how to create a Bode plot in MATLAB.
