摘要
从结构原理上对程控正弦波信号发生器作了新的设计 ,基于微机程控技术与锁相技术 ,采用重复往返地址取码 ,实现了波形的移相和变频 ,并以双极性输出。整机系统稳定性高、准确性好 ,结构模块化 。
This paper describes new design pninciples of the structure of sine ware generator.Based on the technique of program controlling and phase locking,it adopts redesign scouring address recoprocating to implement phase locking and frequency changing,and the out coming signal is bipolar.Since The stability and the accuracy of the system is high,and its construction is modularized,the generator can be operated easily and flexibly.
