Time Domain Analysis of Control Systems

The Fourier Transform is a powerful mathematical tool used to analyze and decompose complex signals into their basic frequency components. It works by transforming a function or signal from the time domain, where it’s described as changing over time, into the frequency domain, where it’s represented by how much of each frequency is present. Essentially, it tells us what frequencies make up a signal and how strong each one is. This makes it an essential concept in physics, engineering, and mathem
