Design and Implementation of Wave Digital Filters

Abstract

One of possibilities of the Wave Digital Filters (WDF) design isusing the classical LC-filters theory. The aim of this paper is todemonstrate the design of WDF from the LC filter and the implementationof WDF on the fixed-point digital signal processor. The theory of wavedigital filter has been developed by using the classical scatteringparameter theory. The theory of ladder filters is well-known, and soour present problem can thus be reduced to a problem how to replace theL and C elements of the filters by adaptors and delay elements, addersand multipliers.
