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’. Default is 'db3'.

a_max : int, optional¶

The maximum scale / level (can be ‘max’ to set according to wmaxlev). Default is 5.

delta : int, optional¶

The sampling period. Default is 1.

Returns:¶

Dictionary containing the level with the highest energy coefficients, the dominant period, and the dominant pseudo-frequency.

Return type:¶
