Question

A driving point impedance with zero at ω = 0 and pole at ω = ∞ must have ___________ term in the numerator polynomial. (a) s^1+ωn^1 (b) s^2+ωn^1 (c) s^1+ωn^2 (d) s^2+ωn^2 I have been asked this question by my college professor while I was bunking the class.

Answer 1

The correct choice is (d) s^2+ωn^2 For explanation I would say: If a pole is at ω = ∞, there will be an equal number of s^2+ωn^2 type terms in the numerator polynomial and the denominator polynomial.
