【摘要】：介绍了一种具有快速硬件自触发功能的数据采集前端的设计,针对大面积多探测点的高能宇宙线实验的特殊情况,提出了独立自触发、数字化和数字滤波的实现方案。通过灵活的板级控制和兼容的PCB管脚设计,提供比较灵活的采样速率和采样精度的调整,以满足不同的需求。通过不同滤波器参数设置,实现对不同干扰信号的排除,完成信号的有效探测。
[Abstract]:This paper introduces the design of a data acquisition front-end with fast hardware auto-trigger function. According to the special situation of high-energy cosmic ray experiment with large area and multiple detection points, the realization scheme of independent self-trigger, digitization and digital filtering is proposed. Through flexible board level control and compatible PCB pin design, flexible sampling rate and precision adjustment are provided to meet different requirements. By setting different filter parameters, the different interference signals can be eliminated and the signal can be detected effectively.
