... Causality for LTI Systems. An LTI system is causal if and only if its impulse response h satisfies h(n) = 0 for n < 0. It is important to remember that this criterion is applicable only to LTI systems. For example, we cannot use this criterion to determine whether systems of Examples 1.2 and 1.3 are ...
