Bode plots

Bode plots are graphical tools used to analyze how a system responds to different input signals at various frequencies. They consist of two plots: one shows how the system amplifies or attenuates signals across frequencies (magnitude), and the other illustrates how the system shifts the signal's timing or phase. Engineers use Bode plots to understand if a system will stabilize or resonate at certain frequencies, helping them design filters, controllers, or systems that perform reliably in real-world conditions. Essentially, they visualize a system’s frequency behavior for better analysis and design.
