A Theorem of I. Schur and Its Impact on Modern Signal Processing
T. Kailath · Operator theory · 1986
An algorithm of Schur for characterizing power series that are bounded in the unit circle is shown to have applications to a variety of problems in science and engineering. These include speech analysis and synthesis, inverse scattering, decoding of error-correcting codes, synthesis of digital filters, modeling of random signals, Padé approximation for linear systems, and zero location of polynomials.
