A band pass digital filter which may be straightforwardly implemented. Considering successive samples I the last of which is N and input samples XI and output samples YI, the filter, in one embodiment, conforms to the expression: YN=2-K+J.(XN-XN-2)-C4.YN-1-YN-2+2-K.YN-2 where J and F are integers. |
