The lowest degree in numerator polynomial and denominator polynomial in a driving point function may differ by at most __________
A. 0
B. 1
C. 2
D. 3
I had been asked this question in class test.
The query is from Properties of Transfer Functions in portion S-Domain Analysis of Network Theory
Right answer is B. 1
The best explanation: The lowest degree in numerator polynomial and denominator polynomial in a driving point function may differ by at most one and the coefficients in the polynomials P(s) and Q(s) of network function must be real and positive.
