摘要
以复杂可编程逻辑器件实现系统计数,采用等精度测量技术,借助PC/AT89C52对30mV～50V、1Hz～100MHz的周期信号,虚拟/智能地完成8×10-6精度的频率/周期测量,同时采用闸门测量技术完成脉宽、占空比的测量,仿真与实验效果好,介绍了系统集成思想与设计方案。
A virual & intellectual count system controlled by PC/AT89C52 was presented,in which CPLD was designed for system's counting,equal precision technology for frequence/cycle measure with 8×10^(-6)precision to input signal 30 mV～50 V,1 Hz～100 MHz,gate measure technology for pulse and cycle duty measure simultaneously,good result was achieved in the imitation and experiment,the system integration thought and design plan were given.
