【摘要】 符合/反符合系统可以使用时间覆盖技术构成,也可以通过信号的时间谱选择技术构成。时间谱是由信号之间的时间差形成的。分析表明,采用信号之间直接覆盖方式的系统比较简单,逻辑关系比较清晰,但不能揭示信号之间的统计分布关系,并对信号的宽度有一定的要求;而时间谱技术的特点正好相反。讨论了两种技术的原理及其差别,并讨论了两种技术各自的优缺点。更多还原

【Abstract】 The Coincident/Anti-Coincident system can be made by two methods,time overlap technique or time spectrum technique.The later is formed by the spaces of the input signals.Studies show that the coincident/anti-coincident system can be setup easily by the time overlap technique.Using the time overlap technique,the logical relationships of inputs and outputs are very clear,but it is difficult to analyse the correlation of statistical distribution between the input signals.Meanwhile,the input signals must satisfy the demand of the minimum pulse overlap time.The time spectrum technique has opposite characteristics.It presents the principles,differences and some specific properties of the two techniques.更多还原
