| Abstract: | Based on the excellence of DDS(direct digital synthesizer),in order to design a sine signal generator with high performance,a design method of signal generator on DDS chip AD9954 is used in the paper.And also the design approach of elliptic function low-pass filter is illuminated particularly.The hardware is achieved finally.The signal generator works in single and swept mode.The capability is as follows:the output frequency range is 100 Hz~110 MHz,and the frequency resolving is 0.1 Hz,the frequency switching interval is 1.5 ms. |
