Problem 44948. Calculate a Damped Sinusoid

Created by Pooja Lalan

Solve Later

The equation of a damped sinusoid can be written as

y = A.ⅇ^(-λt)*cos(2πft)

where A, λ, and f are scalars and t is a vector.

Calculate the output sinusoid y given the inputs below:

lambda - λ
T - maximum value of t
N - number of elements in t

Assume A = 1 and f = 1 . The vector t should be linearly spaced from 0 to T, with N elements.

function y = damped_cos(lambda, T, N)
A=1;
f=1;
t=linspace(0,T,N);

y = A*exp(-lambda*t).*cos(2*pi*f*t);
end
