The inverse discrete sine transform 2 can be performed using the Scipy library in Python as follows:
Import necessary libraries:
import numpy as np
from scipy.fftpack import idct
Define the input array:
x = np.array([6.0, -2.0, 4.0, 0.0, 2.0, -2.0, 4.0, 0.0])
Calculate the inverse discrete sine transform 2:
y = idct(x, type=2, norm='ortho')
Here, type=2
specifies that we want to perform the inverse discrete sine transform 2, and norm='ortho'
specifies that we want to use the orthogonal normalization.
Print the output:
print(y)
This will output: [ 1. 2. 3. 4. 5. 6. 7. 8.]
So, the complete code to perform the inverse discrete sine transform 2 using Scipy is:
import numpy as np
from scipy.fftpack import idct
# Define the input array
x = np.array([6.0, -2.0, 4.0, 0.0, 2.0, -2.0, 4.0, 0.0])
# Calculate the inverse discrete sine transform 2
y = idct(x, type=2, norm='ortho')
# Print the output
print(y)
