摘　　要：在数字振荡器产生任意波形的原理的基础上,提出一种利用改进的数字振荡器算法产生高精度任意波形的方案.这种方案基于DSP(digital signal processing)技术,占用系统资源少,波形参数易于调节.最后利用该方法设计一个基于DSP和PC机的波形参数随时可调的正/余弦发生器,并对工作原理和软硬件设计过程进行了详细叙述.The principle of arbitrary waveform generator using digital oscillator algorithm was introduced.A new solution to generate high precise arbitrary waveform by improved digital oscillator algorithm was also presented.This solution was based on DSP（digital signal processing）,occupancy less system resources,and it was easy to adjust waveform parameter.A parameter adjustable sine/cosine waveform generator based on DSP and PC was finally designed,whose principle and designs of software and hardware were detailed in this paper.
