Fourier Transform Visualized via WebGL

In plain words

Fourier Transform Visualized via WebGL is an interactive tool that displays how Fourier transforms work through animated graphics. It uses WebGL technology to render real-time visualizations of mathematical transformations. The tool is designed for students, educators, and anyone interested in understanding signal processing and mathematical concepts. It makes abstract mathematical principles concrete and observable through dynamic visual demonstrations.

Select two frequencies and see their corresponding exponential basis function on the bottom/blue side of the cuboid. On the top side you can the see the bandpass filtered signal in the time domain, having all frequencies outside of the selected range removed. Explore the interrelation between the time domain of a signal and it's spectrum. The cuboid demonstrates the relationships between time and frequency domains. A 90 degree rotation of the cube represents a Fourier Transform. Taking the Fourier Transform twice results in the original signal flipped along the time axis. This corresponds to a 180 degree rotation i.e. viewing the signal from the backside. A third Fourier transform then…from static.laszlokorte.de
