拓宽函数发生器频率范围的一种简单方法

A Simple Method for Extending Frequncy of Function Generator

采用微机最小系统，用计数器－存储器式数字法生成函数发生器，通过软件上专门的编 程设计获得拓宽函数发生器的频率范围．

A function generator is formed by adopting the minimum system of microcomput- er and using the digital method or Counter-Memory mode. The frequncy extension of func- tion generator is gainned by the programming design to be original in software.
