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]
