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
import numpy as np
gfg = scipy.fft.fftfreq( 5 , 1.096 )
print (gfg)
|
Output :
[ 0. 0.18248175 0.3649635 -0.3649635 -0.18248175]
Example #2 :
Python3
import scipy
import numpy as np
gfg = scipy.fft.fftfreq( 3 , 2.4096 )
print (gfg)
|
Output :
[ 0. 0.13833555 -0.13833555]
