  • in general, we index discrete-time signals from 0 to infinity. In other words, the beginning of a signal is indexed at 0 rather than 1. You can think of it as, 0 is the sample we are currently processing, negatively indexed samples are samples we have already processed, and positively indexed samples are sample we will process. (present, past, and future)
