Causal & Non- Causal System in Hindi....

A system whose output or response at any time instant (t) depends only on the present and past values of the input but not on the future values of the input is called the causal system. For a causal system, the output or response does not begin before the input signal is applied. This is why, a causal system is also called a non-anticipated system.

The causal systems are real time systems and they can be physically realised. For a causal system, the impulse response of the system is zero for negative time..
