Convolution Lab showing two rectangular pulses convolved into a trapezoid, with their spectra
Chapter: Fourier Transform

Convolution Lab

Pick two waveforms and watch convolution happen step by step: flip, shift, multiply and integrate. Switch to multiplication mode to see modulation and sampling, and compare the spectra in both cases.

More demos, for amplitude and frequency modulation, will be added here.
