Accurate parallel form filter synthesis
M. Price, Sean B. Holden, Mark B. Sandler · Electronics Letters · 1996
Standard algorithms for synthesising parallel form digital filters are adequate for basic applications. However, recursive filters required in acoustics synthesis applications often have very high orders, and errors from filter synthesis can become intolerable. The authors describe a new method for synthesising parallel form recursive filters. In the experiment described, the new algorithm yielded smaller errors than the standard technique for almost every filter tested.
