How can I obtain the time constant of the transfer function of a first order system, such as the example below?
$ \frac{C(s)}{R(s)} = \frac{2}{s + 3}$
Where $C(s)$ is the output of the system and $R(s)$ is the input of the system.
I'm not looking for an exact answer, I just would like to be pointed in the right direction as to how to solve for the time constant so that I can solve it myself.
Thanks.
