Let us compute the roots of the polynomial. Any root of modulus one gives rise to an equal-delay component. Such situations are treated in Robinson (1967b)^{[1]}. Here, we assume that there are no roots of modulus one. There are 2*N* roots in all. Of these roots, *N* of them, say, , will have modulus greater than one. The remaining *N* roots will have modulus less than one. Let us form the polynomial
