A system with memory which anticipates future values of input is called _________

Electronics and Communication Engineering (ECE) : Signals and Systems - Quiz(MCQ)

Static System

Causal System

Non-causal System

Non-anticipative System

Correct Answer : Option (C) : Non-causal System

Explanation : A system which anticipates the future values of input is called a non-causal system. A causal depends only on the past and present values of input. Non-anticipative is another name for the causal system. A static system is memory less system.
