title: Fast microcomputer-based multipurpose filtering routine.
abstract: In order to perform high-speed digital signal filtering or differentiating at reduced costs, we developed a 68000 assembler routine which runs on a 68000 coprocessor card in an Apple II computer. It achieves a remarkable saving of computational time and may also be used directly with any 68000-based microcomputer.
