In the last few years some articles have emphasized certain fundamental inconsistencies underlying feedback control theory. The paper of Willems  Georgiou and Smith , later the works of Makila ,, of Leithead et al.  have stressed the inconsistency of standard formalisms of linear time-invariant systems when the signals are double sided and the systems are open loop unstable. We establish a framework for a consistent time domain and frequency domain representation of discrete time linear time-invariant systems and, furthermore, that supports the consistent analysis of discrete time linear time-invariant feedback systems when signals are double sided and the systems are open loop unstable.
