The purpose of this paper is to parallel for digital filters the type of synthesis that might be found in a first course in circuit or control theory. The method described emphasizes the digital formulation as a separate entity rather than a carry-over from one domain to the other by means of conformal mappings. Implementation problems are considered, particularly that of the volume of computation required for operation of the filters.
