A valid immittance function is(a) (s + 4)(s + 8)/(s + 2)(s – 5)(b) s(s + 1)/(s + 2)(s + 5)(c) s(s + 2)(s + 3)/(s + 1)(s + 4)(d) s(s + 2)(s + 6)/(s + 1)(s + 4)I got this question in an online interview.I need to ask this question from Circuit analysis in S domain in portion EDC Overview of Electronic Devices & Circuits

Answer»

The correct CHOICE is (d) s(s + 2)(s + 6)/(s + 1)(s + 4)

The best explanation: a) pole lie on positive real axis

b) poles and zero does not interlace on axis.

c) poles and zero does not interlace on axis.

d) is a valid immittance FUNCTION.
