The Design of Bit-Serial Lattice Wave Digital Filter Using FPGA

Abstract

This article describes an efficient approach to the implementation of bit-serial lattice wave digital filters based on field programmable gate array (FPGA). In this paper, a time schedule of all of the bit-serial two-port adaptors is presented as a bridge between conception and completion. Finally, with the satisfying frequency response, the filter is successfully tested by both computer simulation and real signal measured from the programmed FPGA.
