When it comes to mathematics, the average person can probably get through most of life well enough with just basic algebra. Some simple statistical concepts would be helpful, and a little calculus ...

In Example IV.2.1 we studied the Fourier series for a periodic square wave: Shown below is an animation showing the influence on the addtion of terms in the Fourier series to produce this periodic ...

Built upon the ubiquitous Fourier transform, the mathematical tools known as wavelets allow unprecedented analysis and understanding of continuous signals. In an increasingly data-driven world, ...
