Abstract
Starting from a given polynomial, the Routh algorithm recursively gene rates a family of all-pole transfer functions with the same energy of the impulse response and a suitable number of its derivatives. It is s hown that each of these energies is given by a linear combination of s ome of the others according to the entries of a row of the Routh table for the given polynomial. This fact can be exploited to evaluate cert ain quadratic integrals in an efficient way.
