Question

The driving point function is the ratio of polynomials in s. Polynomials are obtained from the __________ of the elements and their combinations.

(a) transform voltage

(b) transform current

(c) transform impedance

(d) transform admittance

This question was addressed to me during a job interview.

This question is from Properties of Driving Point Functions topic in division S-Domain Analysis of Network Theory

Answer 1

Correct answer is (c) transform impedance

Explanation: The driving point function is the ratio of polynomials in s. Polynomials are obtained from the transform impedance of the elements and their combinations and if the zeros and poles are not repeated then the poles or zeros are said to be distinct or simple.
