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.
 the degree of P (s) is always greater than the degree of Q (s).
 maximum degree of P (s) and Q (s) differ at most by one.
  degree of P (s) is independent of degree of Q (s).
