21 Fourier Series Representations (Example 2)

Peter Math on Instagram: "The Fourier Transform is a fundamental mathematical tool used to analyze and understand signals by breaking them down into their basic frequency components. Instead of focusing on how a signal behaves over time, the Fourier Transform shifts the perspective to how much of each frequency is present in that signal. This is especially useful in fields like signal processing, audio engineering, and even quantum physics, where understanding how different frequencies contribut
