I have a transfer function for system.(adsbygoogle = window.adsbygoogle || []).push({});

23.23*s + 1.421

------------------------------------- = tf

s^2 + 25.88*s + 1.421

Since the numerator has a non-zero coefficient for "s" I am wary about equating

25.88 = 2 * zeta * omega [the stuff we usually do for calculating the damping ratio].

Can someone shed any light on this?
