Question

The coefficients in the denominator polynomial of the transfer function must be?

(a) positive

(b) negative

(c) positive or zero

(d) negative or zero

I got this question in an online quiz.

I need to ask this question from Properties of Transfer Functions in chapter S-Domain Analysis of Network Theory

Answer 1

Correct choice is (a) positive

For explanation I would say: The coefficients in the denominator polynomial of the transfer function must be positive but should not be negative and the coefficients in the polynomials P(s) and Q(s) of transfer function must be real.
