Hit the "Fourier" button, and it will calculate all of the Fourier coefficients F(ω k) and display it in a plot to the right. Hit the "Log" checkbox and it will display in a log scale.

Sine and cosine waves can make other functions! Here two different sine waves add together to make a new wave: You can also hear it at Sound Beats.

This site is designed to present a comprehensive overview of the Fourier transform, from the theory to specific applications. A table of Fourier Transform pairs with proofs is here.

Joseph Fourier studied the mathematical theory of heat conduction. He established the partial differential equation governing heat diffusion and solved it by using infinite series of trigonometric …

The Fourier Transform is a mathematical tool that breaks down complex signals or functions into simpler, frequency-based components. Imagine you have a musical note—it’s a combination of …
