The Method of Realizing Wave Compression in DDS
Wang Cheng-jing · 2005
Direct Digital Frequency Synthesizer is widely applied in modern electrical system and the frequency design of equipment. Downloading the DDS design to the FPGA enables the system more available. How to use limited the hardware resource of FPGA and get fast and qualified DDS are problems which we have to face. This essay introduces a method of using the wave compression to save FPGA resources, and this method can be applied in the design of Direct Digital Frequency Synthesizer(DDS). The hardware testing proves that this method is valid and successfully fulfils the design requirement. In this essay, we provide the principle and circuit structure of the method.
