Title

Causality and Delay and Physics in Real Systems

Abstract

In the present work causality property and physics behind it is analyzed for physical systems. Different methodologies for checking or enforcing causality in both time and frequency domain are discussed. Causality metric for measuring causality violation is introduced. Physical anomaly of a system with perfectly linear phase is discussed and shown that small perturbation of non-linear portion of the phase can fix the non-causal anomaly.
