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.
# 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 :
# 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]
