Can a causal system be stable?
thus must be zero before time zero. Certainly, all physical systems operating in real time must be causal. is finite, then the impulse response damps out quite rapidly, and we say that the system is stable.
What is causal and anticausal system?
A causal system is one whose output depends only on the present and the past inputs. A noncausal system's output depends on the future inputs. In a sense, a noncausal system is just the opposite of one that has memory.
What is difference between non-causal and Anticausal?
A system that has some dependence on input values from the future (in addition to possible dependence on past or current input values) is termed a non-causal or acausal system, and a system that depends solely on future input values is an anticausal system.
When the system is stable in Z transform?
The stability of a system can also be determined by knowing the ROC alone. If the ROC contains the unit circle (i.e., |z| = 1) then the system is stable.
