This module is very interactive, and does a good job of tying the mathematics to practical applications (image processing and signal processing).
Page-Specific Suggestions:
The module's applets do a great job of reinforcing the material while entertaining the user. There are only a few minor bugs/recommendations; these are brought to the attention of links programmers in a later section.
