pulse timing circuit

This paper introduces the circuit realization of a fast timing discriminator. Its input signals can be non-inverting or inverting signals of every kind of voltage level while its output is multi-channel negative standard NIM signal with adjustable pulse width.

介绍了一种快速定时甄别器的电路实现，输入可以是各种电平的正相或者负相信号，输出是多路脉冲宽度可调的负相标准NIM信号。

In the design of the main oscillating circuit, the programmable timing counter IC of 8254 is controlled by the single chip computer to adjust the pulse width and interval, which provides the precise adjustment on the pulse width and interval in a wide range.

在主振脉冲发生电路的设计上，通过单片机控制可编程定时计数器芯片8254来控制脉冲宽度和脉冲间隔，使脉冲宽度和脉冲间隔在很宽的范围内可以精确调节。
