一种数字式相位脉冲发生器

A Digital Phase Pulse Generator

本文介绍一种新颖的脉冲信号源,它采用非线性反馈移位寄存器产生脉冲序列,通过改变移位寄存器的反馈函数来改变脉冲参数.因此,输出脉冲的周期、宽度、延迟时间精度高、量程大、数字化,并能给出两路输出脉冲间的相位差,具有一般脉冲发生器所没有的一些功能.

A Pioneer Pulse generator is described in this article.This instrument has been well-designed with non-linear feedback shift registers to produce pulse trains.pulsc parameters are adjustable by changing feedback functions of the shift rcgistcrs, thus making the generator capable of delivering pulses with digital high preccsion cycle, width and delay variable in wide range, and also giving the phase difference between output pulses from two channels. There are unique functions available from this generator while unavailable from its predecessors.
