Abstract :
This paper presents a universal structure for wave digital filters. These universal structures can be modified to achieve any desired digital frequency specifications by simply changing the value of the structure multipliers without altering the overall structure. Utilizing these structures, it becomes feasible to realize digital filters with simultaneously varying bandwidth and center frequency.
