What is an example of causal system?
a) y(t)=x(t)
Here, the signal is only dependent on the present values of x. For example if we substitute t = 3, the result will show for that instant of time only. Therefore, as it has no dependence on future value, we can call it a Causal system.
Which system is anti causal?
An acausal system is a system that is not a causal system, that is one that depends on some future input values and possibly on some input values from the past or present. This is in contrast to a causal system which depends only on current and/or past input values.
What is non causal system with example?
The non-causal systems can generate an output before the input is given, hence they are also known as anticipative systems. The non-causal systems do not exist in real time. Also, these systems are not physically realisable. The image processing systems are the examples of noncausal systems.
What is causal and anti causal 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. How can a real-world system be noncausal? It cannot because real systems cannot react to the future.
