Webclass pywt.Wavelet(name[, filter_bank=None]) ¶ Describes properties of a discrete wavelet identified by the specified wavelet name. For continuous wavelets see pywt.ContinuousWavelet instead. In order to use a built-in wavelet the name parameter must be a valid wavelet name from the pywt.wavelist () list. WebThe fundamental frequency of this wavelet in Hz is given by: f = w*fs / (2*s*np.pi) where fs is the sampling rate and s is the wavelet width parameter. Similarly we can get the wavelet width parameter at f: s = w*fs / (2*f*np.pi) Examples >>> import numpy as np >>> from scipy import signal >>> import matplotlib.pyplot as plt
