摘　　要：介绍了数字/轴角转换器的工作原理,提出了基于ROM正弦发生器和斯科特变压器的低成本设计方案及误差分析步骤.描述了电路物理构成及其运行原理,并在讨论整个主要误差来源的基础上对比2种常用测试方案的优劣,最终给出最优误差测试策略及电路校正优化实现方案.实验结果显示,通过误差测试方案校正的该数字——自整角机转换器的转换精度可达±2′以内,证明了此低成本设计方案的可行性,其测试优化电路的设计简单,调试方便,具有一定的实用价值.The operation principle and error analysis approach of a circuit module for converting digital angle to axisangle are introduced. The digital synchro converter （DSC） design,which has features of low cost and high precision is based on ROM and Scott transformer. Two different concrete testing and optimization proposals were given when the design structure was completed. The optimized testing scheme was detailed after discussing main error resources of DSC. The experiments indicated that this design and testing proposal, which are convenient and pellucid, have been proved to achieve the precision within ±2＇ and so the feasibility for practical realization.
