The stability of Periodically Shift Variant (PSV) filters are studied when implemented with two's complement truncation (TCT) quantization. Block form and standard (non block) form implementations are considered and two sufficient conditions are established for stability. As a special case, second-order coupled-form PSV filters are then investigated under TCT quantization. Stability regions are established within the parameter space for two different types of block implementations. Examples are given to illustrate the results.
