pyhctsa.operations.wavelet.scal_2_freq¶ pyhctsa.operations.wavelet.scal_2_freq(y, w_name='db3', a_max=5, delta=1)¶ Frequency components in a periodic time series. Parameters:¶ y : array-like¶The input time series. w_name : str, optional¶The name of the mother wavelet to analyze the data with: e.g., ‘db3’, ‘sym2’. a_max : int, optional¶The maximum scale / level (can be ‘max’ to set according to wmaxlev) delta : int, optional¶The sampling period. Returns:¶ Dictionary containing the level with the highest energy coefficients, the dominant period, and the dominant pseudo-frequency. Return type:¶ dict
