Stability of digital filters implemented with two's complement truncation quantization
Tamal Bose, M.-Q. Chen · IEEE Transactions on Signal Processing · 1992
The stability of digital filters implemented with two's complement truncation quantization is investigated. Both the direct-form and normal-form realizations are considered and regions in the parameter plane are obtained where the filters are globally asymptotically stable. Regions within the stability triangle of a direct-form digital filter are also studied where limit cycles of period one and two are possible. The results are illustrated with several examples.>
