Homework Statement
I am reading a little bit on Causal LTI systems. I know causality means that a system cannot depend on the future, but why does that mean an impulse function, say
h(t) = 0, for all t<0
I mean, if t is negative, then it's not really depending on the future, but the past right? Or am I visualizing this wrong?
