scipy.fftfreq() in Python
With the help of scipy.fftfreq() method, we can compute the fast fourier transformation frequency and return the transformed array by using this method.
Syntax : scipy.fftfreq(n, freq)
Return : Return the transformed array.
Example #1 :
In this example we can see that by using scipy.fftfreq() method, we are able to compute the fast fourier transformation frequency and return the transformed array.
Python3
# import scipy and numpy import scipy import numpy as np # Using scipy.fftfreq() method gfg = scipy.fft.fftfreq(5, 1.096) print(gfg) |
