Python | Numpy np.ifft () method

NumPy | Python Methods and Functions

Using the np.ifft() method, we can get 1-D inverse Fourier transform using np.ifft ( ) .

Syntax: np.ifft (Array)
Return: Return a series of inverse fourier transformation.

Example # 1:
In this example we can see that using np.ifft () , we can get a series of inverse Fourier transforms using this method.

# NumPy import

import numpy as np

 

a = np.array ([ 5 , 4 , 6 , 3 , 7 ])

# using the np.ifft () method

gfg = np.fft.ifft (a)

 

print (gfg)

Output:

[5. + 0.j 0.2236068 - 0.21796276j -0.2236068 - 0.92330506j
-0.2236068 + 0.92330506 j 0.2236068 + 0.21796276j]

Example # 2:

# NumPy import

import numpy as np

  

a = np .array ([ - 5.5 , 4.4 , - 6.6 , 3.3 , - 7.7 ])

# using the 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 - 1.1377 4197j]
