Filters some input data using wavelets. Center frequency and bandwidth of wavelets is defined by the user. Output consists of the input signal following the wavelet-based filtering, the wavelets used for the filtering, and the peak-to-peak amplitude of all wavelet-filtered signals. The filtering of the input signal with a wavelet is achieved by performing a convolution of the input signal and wavelet in the frequency domain (i.e. a multiplication of both signal's FFTs).

Dear author,

Thank you for your sharing. It is an efficcience function.

Please, have you got an journal paper (scientific references) about your application?

Thank you very well!

Filtering now achieved by performing a convolution of the input signal with the wavelets in the frequency domain, thus dramatically decreasing computation requirements.
