Digital Filters - IV. We now turn to recursive filters. It will be seen from the first formula that we have values on only one side of the current value n, and that we use both old and the current signal values, and old values of the outputs. This is classical, and arises from the fact that we are often processing a signal in real time and do not have access to future values of the signal.
