Hey everyone, I have a transfer function which is:
$H(S) = \frac{2}{3s} - \frac{1}{s+2} + \frac{1}{3(s+3)}$

I would like to know the relationship between H(S) $\Longleftrightarrow$ h(t) because I am required to find h(t).

I know that the solution is: h(t) = $\frac{2}{3}u(t) - exp(-2t) + \frac{1}{3}exp(-3t)$

Thank you!

Okay I just solved this. Let me know if anyone would like to know how I did it.

How would I go about drawing the above function of h(t)? Graphical calculator is not allowed also!

Perhaps I should think a little more before posting. No need to help me on this post but message on here if you would like to know how to do it! Sorry..

Sometimes talking about a problem makes it easier to solve it. Don't know why that is, but it seems to be often true.

We don't mind listening.
