Python | Numpy np.fft() method
With the help of np.fft()
method, we can get the 1-D Fourier Transform by using np.fft()
method.
Syntax : np.fft(Array)
Return : Return a series of fourier transformation.
Example #1 :
In this example we can see that by using np.fft()
method, we are able to get the series of fourier transformation by using this method.
import numpy as np
a = np.array([ 5 , 4 , 6 , 3 , 7 ])
gfg = np.fft.fft(a)
print (gfg)

Output :
[25. + 0.j 1.11803399 + 1.08981379j -1.11803399 + 4.61652531j
-1.11803399 – 4.61652531j 1.11803399 – 1.08981379j]
Example #2 :
import numpy as np
a = np.array([ - 5.5 , 4.4 , - 6.6 , 3.3 , - 7.7 ])
gfg = np.fft.fft(a)
print (gfg)
|
Output :
[-12.1 + 0.j -3.85 – 5.68870985j -3.85 – 16.52766106j
-3.85 + 16.52766106j -3.85 + 5.68870985j]
