Control Systems For a transfer function H (s) = P(s) / Q(s), where P (s) and Q (s) are polynomials in s. Then the degree of P (s) and Q (s) are same. degree of P (s) is independent of degree of Q (s). maximum degree of P (s) and Q (s) differ at most by one. the degree of P (s) is always greater than the degree of Q (s). the degree of P (s) and Q (s) are same. degree of P (s) is independent of degree of Q (s). maximum degree of P (s) and Q (s) differ at most by one. the degree of P (s) is always greater than the degree of Q (s).
