It is shown how with analogy to analogue control theory, that the problem of polynomial-matrix spectral factorisation can be solved using negative feedback. This recursive method is particularly simple to implement compared with other approaches. The algorithm in its basic form requires no matrix inversions or special matrix decompositions.
