An anticausal system is a hypothetical system with outputs and internal states that depend solely on future input values. Some textbooks [1] and published research literature might define an anticausal system to be one that does not depend on past input values, allowing also for the dependence on present input values. A causal system is one in which the output depends only on current or past inputs, but not future inputs. Similarly, an anticausal system is one in which the output depends only on current or future inputs, but not past inputs. Finally, a noncausal system is one in which the output depends on both past and future inputs. All "realtime" systems must be causal, since they can not have future

All "realtime" systems must be causal, since they can not have future only the fundamental solution of a system into account, the mixed causal-noncausal autore- gressive model explicitly allows for nonfundamental outcomes, as the process of interest might depend on past, current and future (nonfundamental) shocks.

Since non-causal system contains future samples; a non-causal system is practically not realizable. That means in practical cases it is not possible to implement a non-causal system. That means in practical cases it is not possible to implement a non-causal system. Although physical systems are always causal, it is desirable to remove this requirement because an artificial noncausal multiplier may be introduced into the analysis as a mechanism for reducing the conservativism of the resulting absolute stability conditions. The main result of the paper is the derivation of sufficient conditions for stability of the feedback interconnection of an interval
