Abstract :
A new decomposed version of three-port adaptors for wave digital filters (WDFs) is proposed, which is especially suitable for floating-point arithmetic and for implementation on digital signal processors (DSPs). By using the proposed three-port adaptor, the concept of modified wave digital filters (MWDFs) is appropriately extended to WDFs involving any n-port adaptors (n is integer). The resulting MWDFs preserve all the important properties of WDFs, in particular, those relating to stability
