Design and Implementation of a Controllable DDS Orthogonal Signal Generator based on MATLAB

This paper introduces a designed and realized method about the controllable directly digital synthesizer,which is based on the MATLAB.In this paper,we gave a briefly analysis on the concept of the DDS and a math model in the MATLAB.In the meanwhile,used the hardware description language to realize and verify this model on a fugal chip.The design can suit the front-end equipments and other digital signal process domain.
