摘　　要：介绍以复杂可编程逻辑器件实现系统测量ASIC,借助51TM单片机控制完成对50mV～50V、0.1Hz～100MHz的正弦波、矩形波等周期信号的频率、周期、占空比、脉宽和计数的全自动化测量系统的设计原理与实现方法。实验表明这是一种功能多、精度高、体积小、且具有特殊功能的性价比很高的智能化仪器。An automatical measuring system was introduced,which used CPLD for measuring ASIC and 51TM single microcomputer for control,by which common signal parameters were measured automatically such as frequency,cycle,cycle duty,count,pulse width to cycle signal such as sine wave,rectangle wave etc.,input signal voltage ranged from 50mV to 50V and frequency 0.1Hz to 100MHz. The system's design principle and realizing method were given,the experiments showed the system was a intellectual instrument of multifunction,high precision,small volume,special function and high performance/price ratio.
