It is shown that a Luenberger observer may be used to convert a transfer function having a numerator of degree m and a denominator of degree n (with mn−1) into one having a numerator of degree n+m−1 and a denominator of degree 2n−1, with the denominator polynomial and n−1 of the numerator coefficients assignable arbitrarily.
