Learn how to use Fourier series with Massachusetts Institute of Technology (MIT) Prof. Gilbert Strang! | MATLAB

The Fourier series is a mathematical tool that expresses a periodic function as the sum of simple sine and cosine waves. Each component wave, called a harmonic, has a specific frequency, amplitude, and phase, and together they reconstruct the original function. By breaking down complex waveforms into these fundamental trigonometric components, the Fourier series allows us to analyze signals in the frequency domain and understand how different frequencies contribute to the overall shape of the wa
