Prerequisites for understanding Wavelet theory

Question

I have a degree in computer science and I have taken the following math courses.

• Calculus I

• Calculus II

• Discrete Mathematics and Number Theory

• Linear Algebra

• Probability

• Logic

• Automata Theory

What other courses should I take in order to prepare for studying wavelets, with a focus on implementing wavelet transforms?

Answer 1

Wavelets are taught usually as filter banks. This means you need to know Fourier transforms (all kinds), and DSP (all sorts of filtering techniques) properly. Wavelets follow naturally after this. I would recommend signal processing or some similar course that covers Fourier transforms and the like. Besides being useful as a foundation for wavelets, Fourier theory will give you a new way of looking at data that is often useful.
