    In this article, we propose a new approach to determining the best rational approximation of a given irrational power spectral density defined on the unit circle such that the approximant has McMillan degree less than or equal to some positive integer $n$. The main result is that we prove the existence of an optimal solution and that this solution can be found by standard methods of optimization.
