摘要
将目前采用的存储波形数据的ＥＰＲＯＭ改为ＳＲＡＭ，利用单片机根据移相要求，随时修改ＳＲＡＭ储存内容，则在相同抽样速率下，可得到比目前采用的调相方法高得多的调相精度。
The paper presents a new phase regulating method,in which SRAM is used in stead of Eprom for storing waveform data and the single chip processor is utilized to update the data stored according to the phase shift requirements.By this method,the phase regulation accuracy can be considerably enhanced in comparison with the conventional method.
