Wavelet transform for time-frequency representation and filtration of discrete signals
Waldemar Popiński · Applicationes Mathematicae · 1996
A method to analyse and filter real-valued discrete signals of finite duration s(n), n=0,1,...,N-1, where $N=2^p$, p>0, by means of time-frequency representation is presented. This is achieved by defining an invertible discrete transform representing a si
