How to compute the impulse response from a transfer function


Say I have a transfer function, for example:



H(z)=11+0.1z30


How can I compute the impulse response?


(This is just an example, the important thing is that it is in closed symbolic form!)


If I understand correctly, if I could just rewrite H(z) as some polynomial in z1 (by using a Taylor expansion), I could just read off the coefficients.


But is there another way?
