| Abstract: | In this paper, a kind of reconfigurable multi-channel DDS signal generator based on FPGA is introduced. The principle, design method, hardware circuit and program of reconfigurable DDS technology is expounded, and the multi-channel structure is designed. In the signal generator, any signal from the host controller can be downloaded into flash ROM and reeonfignred, and the sample point number can be chosen according to signal frequency and this design is valuable in engineering application. |
