Find the impulse response of a system with transfer function H(S) = (s+3)/(s^2+2s+1)
Poles are s1=s2=-1
y = Ae^st + Be^st
The Attempt at a Solution
In my notes I do not have an answer for the case when there is only one pole (root) to the denominator of the transfer function.
I know the cover-up method and it doesn't look like it will work here.
Also tried solving for the step response and differentiating to get the impulse response as shown here: http://tinyurl.com/c5uhzcv
But I cannot find the step response that way either. Thanks!
