Theory of filtering and time series processing L. Zotov Laboratory work ?4 Purpose: Studying wavelet analysis of signals. We use Matlab software (look into the Lab N1). 1) Download program for the lab from http://lnfm1.sai.msu.ru/grav/english/lecture/filtering/ Study the wavelet transform of the signal with changing frequency content. Use different types of wavelets. Change the signal. Include the impulse, study the triangle of its influence on the wavelet coefficients.
