Limit cycles in zero input digital filters due to two's complement quantization
Tamal Bose, David P. Brown · IEEE Transactions on Circuits and Systems · 1990
Limit cycles in zero-input N-order digital filters due to two's-complement truncation quantizers are investigated. A necessary condition and a sufficient condition for the existence of such limit cycles are presented. For the case of period one and period two, a necessary and sufficient condition is established. Some illustrative examples are given.>
