Do you remember the playground see-saw? Imagine you and your friend are on either side of the see-saw. When one of you goes up, the other goes down. This is a bit like a bode plot.
A bode plot shows how much a particular signal changes (like going up and down on the see-saw) at different frequencies (how fast the see-saw moves).
On a bode plot, the horizontal axis shows the range of frequencies that are measured, and the vertical axis shows the amount of change that is measured.
The bode plot is often used in engineering to analyze and design electronic or mechanical systems. By looking at the bode plot, engineers can tell how a system will behave at different frequencies and make adjustments to ensure it functions properly.
So, just like you and your friend needed to balance the see-saw in the playground, engineers use bode plots to balance the systems they work on.
