This simple case of convolution clearly illustrates the mechanics of convolution. Two box functions are displayed on a signal graph and their area of overlap (which, for the box function, corresponds to the value of the convolution at a particular point) is shaded. Students can drag one box of the other, and see how the area of overlap changes and corresponds to the value of the convolution at that point.
Audience
Students learning about the fundamentals of convolution.
Usage
Drag one box of the other, observing how the area of overlap changes and corresponds to the value of the convolution at that point.
