Question

The degree of numerator polynomial in a transfer function may be as small as _________ independent of the degree of the denominator polynomial.

(a) 1

(b) 2

(c) 0

(d) 3

Answer 1

The correct choice is (c) 0

To explain: The degree of numerator polynomial in a transfer function may be as small as zero, independent of the degree of the denominator polynomial and for the voltage transfer ratio and the current transfer ratio, the maximum degree of P(s) must be equal to the degree of Q(s).
