You don't get into the whole field of two-sided Laplace transforms and noncausal-but-stable systems until you revisit signal processing at the graduate level. So -- it's OK if what Peter is saying is new to you. But it's still true, and has practical use (in that you can approximate a non-causal response with delay plus a truncated-from-the-left impulse response). | |
