WebJan 30, 2024 · Clearly, causality is a property of the system, so it cannot depend on the input signal. A causal linear time-invariant (LTI) system is characterized by an impulse response h ( t) that satisfies h ( t) = 0 for t < 0, and it is irrelevant whether the input signal is zero before a certain time or not.

WebShift-invariance: this means that if we shift the input in time (or shift the entries in a vector) then the output is shifted by the same amount. Mathematically, we can say that if f(~ x (t)) = ~y (t), shift invariance means that f(~x (t+⌧)) = y(t+⌧). These two properties are independent: e.g., f(x(t)) = x(t)2 is shift-invariant but not ...
