Homework Statement
What is a wavelet?
Homework Equations
Here is the Haar wavelet mother waveley function:
<tex>\{ t \mapsto \psi(2^n t-k) ; n \in \N, 0 \leq k < 2^n\}</tex>
The Attempt at a Solution
Wavelets are used for analysis. There is a wavelet function and a scaling function. There are also mother and daughter wavelets.
Everything I see talks about what a wavelet does. I can't seem to find very much written about what a wavelet is. I'm not concerned about the application, I'm just looking for a clear definition.
