pydsm.ft.fft_centered¶

pydsm.ft.fft_centered(x, fs=1)¶

Computes a centered FFT.

Provides an FFT function where the output vector has the zero frequency at its center. This is more suitable for plotting.

Parameters:

Parameters:	x : array_like 1-D sequence to compute the FFT upon Returns —— X : ndarray samples of the DFT of the input vector ff : ndarray vector of frequencies corresponding to the samples in X
Other Parameters:
	fs : real, optional sample frequency for the input vector (defaults to 1)

x : array_like

1-D sequence to compute the FFT upon

Returns

——

X : ndarray

samples of the DFT of the input vector

ff : ndarray

vector of frequencies corresponding to the samples in X

Other Parameters:

fs : real, optional

sample frequency for the input vector (defaults to 1)
