The document discusses using exponential attenuation to model the interference of waves. It defines a function that represents the interference of two waves with different frequencies that are attenuated by an exponential term. The function is evaluated over a range of values to model the receiving and interference of the attenuated waves.

1. We use ex as attanuation of waves.
import numpy as np
y=np.arange(0,2*pi,0.2)
f(x)=exp(-x)*(sin(1.2*x)+sin(3*x))
So we have the interference of these waves to be the mapping
x → (sin (1.20000000000000 x) + sin (3 x))e(−x) .
And Receiving
f (y) = [0.0, 0.66, 0.93, 0.9, 0.67, 0.39, 0.17, 0.03, −0.01, 0.01, 0.05, 0.09, 0.1, 0.08, 0.04, −0.0, −0.03, −0.05, −0.05, −
