本文介绍采用三个雪崩晶体管的脉冲发生器线路,在线路中由于用锯齿讯号来驱动雪崩晶体管,因而不必再采用延迟线。这个脉冲发生器是用来以两个或三个脉冲构成的脉冲组合测试10毫微秒的十进制计数器的响应。它带有一个内部发生的同步脉冲,能单独调整延迟,向共输出端传送由二个或三个宽度为几毫 This article describes a pulse generator circuit that uses three avalanche transistors, eliminating the need for a delay line by driving the avalanche transistors with a sawtooth signal in the circuit. This pulse generator is used to test the response of a 10-nanosecond decimal counter with a pulse combination of two or three pulses. It comes with an internal synchronization pulse, can adjust the delay alone, to the common output by two or three widths of a few milliseconds
