Time-Invariant System The system is time invariant if the behaviour and characteristic of the system are fixed over time. In other words, a system is said to be time invariant if a time shift in the input signal causes an identical time shift in the output signal. It means that for continuous time if x(t) → y(t), then x(t-to) → y(t-to) … Read more
Linear System A system is said to be linear if superposition principle is applicable to the system. Superposition Principle The response resulting from several input signals can be computed as the sum of the responses resulting from each input signal acting alone. Let x1(t) and x2(t) be the two inputs. The corresponding responses/output are y1(t) … Read more
Causal Signal A signal that does not start before t=0 is a causal signal i.e. x(t)=0, ∀ t<0. Note: A system is causal or non-anticipatory if the output at any time to depends only on the values of the input at the present time and in the past. You can read about causal and non-causal … Read more
