| Abstract: | This paper introduces the design idea of function generator with multiple functions based on DDS technology.It can export five basic waveforms of higher precision,such as sine wave,cosine wave,triangular wave,sawtooth wave and square wave.The designing and simulation are realized by the Quartus Ⅱ software and MATLAB.The structure of the design is simple.The designing and modifying are convenient and rapid.The system stability and reliability are relatively high.Function calculators with higher precision can be realized if the ROM structure and the laws of function value are fully considered. |
