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)

Output :

[ 0.          0.18248175  0.3649635  -0.3649635  -0.18248175]

Example #2 :

Python3

# import scipy and numpy
import scipy
import numpy as np

# Using scipy.fftfreq() method
gfg = scipy.fft.fftfreq(3, 2.4096)

print(gfg)

Output :

[ 0.          0.13833555 -0.13833555]
