Designing simple, effective digital filters
D.W. Tufts, David B. Rorabacher, W.E. Mosier · IEEE Transactions on Audio and Electroacoustics · 1970
Models for a class of narrow-band digital filters and a class of wide-band digital filters are developed and analyzed The analysis forms a basis for a computer-aided design technique for such filters. Our aim is to show that useful performance can be achieved within the constraints of very simple realizations.
