随机脉冲信号数据采集触发电路设计

Design of Trigger Circuit Based on Random Pulse Signal Acquisition System

针对随机脉冲信号采集中的触发信号获取问题设计了一种快速触发检测系统。利用积分求和方式在获取到随机脉冲触发信号的同时有效地避免了随机噪声的干扰。利用CPLD的逻辑控制与运算功能实现了对随机脉冲信号的快速检测,经电路模拟仿真证明了该触发系统的有效性。

Focused on the problem of getting the trigger in random pulse signal data acquisition, a rapid trigger detection system was designed. The random pulse signal was detected by the integral arithmetic, and at the same time the random noise jamming was avoided. The trigger detection circuit of random pulse signal was designed with CPLD, and proved to work normally and effectively by the circuit simulator.
