electricpy.sinfilt¶

electricpy.sinfilt(arr, Srate, domain=False)[source]¶

Sine Filter Function.

Sine Filter function for filtering a dataset representing a sinusoidal function with or without harmonics to evaluate the fundamental value.

Parameters:¶

arr : numpy.ndarray¶

The input data array.

Srate : int¶

Sampling rate for dataset, specified in number of values per fundamental cycle.

domain : bool, optional¶

Control argument to force return of x-axis array for the filtered data.

Returns:¶

• sinf (numpy.ndarray) – Sine-filtered data

• xarray (numpy.ndarray) – X-axis array for the filtered data.
