随着电子测量技术的日益发展,计数电路的应用也愈来愈广.目前电子仪器除了向扩大量程,提高精度、灵敏度、稳定度,实现小型化,并向组合化、系统化等方向发展外,还有一个新的发展方向,那就是数字化.在测量仪表中实现数字化是提高精度最有效的方法.数字式仪表都是由电子计数电路来完成精确的计量功能的,在计算机中计数电路可作为数码存储,在核物理中也得到广泛应用,它不仅能用来记录辐射探测器所产生的脉冲数目,还可用来记录符合数及反符合数.2~n进位的计数电路虽比较节省电子管,结构简单,
With the continuous development of electronic measurement technology, the application of counting circuit is also getting wider and wider.Nowadays, electronic instruments not only expand the range, improve accuracy, sensitivity and stability, and achieve miniaturization, but also develop toward combination and systematization , There is a new direction of development, that is, digitization.Digitalization in measuring instruments is the most effective way to improve accuracy.Digital instruments are electronic counting circuit to complete the precise measurement function, in the computer counting circuit can be As a digital storage, it is also widely used in nuclear physics. It can not only record the number of pulses generated by the radiation detector, but also record the coincidence number and the anti-coincidence number. ,Simple structure,
