Python | Numpy np.ifft() method
With the help of np.ifft() method, we can get the 1-D Inverse Fourier Transform by using np.ifft() method.
Syntax :
np.ifft(Array)
Return : Return a series of inverse fourier transformation.
Example #1 :
In this example we can see that by using np.ifft() method, we are able to get the series of inverse fourier transformation by using this method.
# import numpy import numpy as np a = np.array([5, 4, 6, 3, 7]) # using np.ifft() method gfg = np.fft.ifft(a) print(gfg) |
Output :
[ 5. + 0.j 0.2236068 – 0.21796276j -0.2236068 – 0.92330506j
-0.2236068 + 0.92330506j 0.2236068 + 0.21796276j]
Example #2 :
# import numpy import numpy as np a = np.array([-5.5, 4.4, -6.6, 3.3, -7.7]) # using np.ifft() method gfg = np.fft.ifft(a) print(gfg) |
Output :
[-2.42 + 0.j -0.77 + 1.13774197j -0.77 + 3.30553221j -0.77 – 3.30553221j
-0.77 – 1.13774197j]
