| Abstract: | The constitute of the direct digital synthesis(DDS) was described. Six channels railway FSK signal generator based on DDS was designed for debugging command of the domestic railway signal equipment. The hardware construction and the algorithm flow were also presented, at the end the precision of the generating signal was analysed. |
