Play interactively with different waveforms, apply Fourier filters,
listen to them
Play interactively with convolution using functions that you can create yourself using the mouse.
The joy of convolution
Play interactively with convolution using different functions
Fourier Transform and Diffraction
Watch the behaviour of diffraction patterns using slits with varying sizes,
using light with different wavelengths
Fourier Transform Experimentation
Play with Fourier transforms on 2-D images, where you may use your own
images; apply various filters in the Fourier domain and see the results
in the image domain
Interactive Fourier Transform
Use gif images and play with the FFT. Filter them in various ways.
Watch the reception pattern of a linear array with a varying number of
elements, element separation, and phase shift
Virtual Radio Interferometer
Play interactively with various interferometers that actually exist.
Use different sources and (u,v)-coverages to see the effect of such
incomplete apertures on the resulting images.
