Question
The differential equation y"(t) + 5y'(t) + y(t) = x(t)
describes a system. Let the system be initially at rest,
y(0*) = y'(0*) = 0, and let the input signal x(t) = 3u(t).
What are the system outputs at t = 1,5, y(1,5)?
%3D
%3D
%3D
Hint: Find natural response. Find forced response (We
have constant input. Its value is 3). Then using initial
condition, you can find coefficients of natural response.
Then you can find y(1,5).
