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]
