ssapy_toolkit.Compute.fft

Functions

`FFT`(data[, time_between_samples])	Perform a Fast Fourier Transform on the input data.
`FFTP`(data[, time_between_samples])	Perform a Fast Fourier Transform and calculate the period.

ssapy_toolkit.Compute.fft.FFT(data: ndarray, time_between_samples: float = 1) → ndarray[source]

Perform a Fast Fourier Transform on the input data.

Parameters: data (np.ndarray): The input time-series data. time_between_samples (float): Time interval between data samples.

Returns: tuple: The frequency array and the FFT result.
