Hello people!

The equation that I am trying to find the poles and zeros is:

\(\frac{(s^\2 + 1)(s^\2 + 4)}{(s^\2 + 9)(s^\2 + 16)}.\frac{1}{s}\)

From what I know, a pole is when the function goes to ∞. Would that mean that

s =0 as that would result in \(\frac{4}{0}= infinity\)

Then for the zeros, I would solve for s to give \(s = +-j, +-2j, +-3j, +-4j\)

Actually I think this is correct so let me pose this question. How would I know weather this function could be used as a driving point impedance? (Not actually fully sure what a driving point impedance is either...)

Thanks!
