A transfer function H(S) in s-domain has been obtained as(adsbygoogle = window.adsbygoogle || []).push({});

H(s) = 5.0625/(0.0008s^2 + 0.0882s + 5.0625). I’m interested in finding its poles and zeros.

I found that denominator polynomial 0.0008s^2 + 0.0882s + 5.0625 has complex conjugate roots. Roots are -55.13 + i 57.35 and -55.13 - i 57.35. I was expecting real valued poles but they are complex poles and it made me doubtful about the correctness of my solution for the poles.

And what about the zeros? Are the zeros at infinity because numerator is a constant quantity?

Would anybody help me in this regard?

Thanks
