数字测速方法及其电路

本文系统地介绍了四种测速方法。其中 M 法、T 法、M/T 法是人们已经熟悉的。文中提出了如何使线路最简的实例。对 KT 法,较系统地介绍了其原理和电路,它是一种在很宽范围都有很高的测速精度和最小计算量的测速方法。对四种测速方法都进行了评价。

The Methods for Speed Digital Measurement and Their Circuits

This paper gives four methods for speed measurement in a systematic way.Among them,M method,T method and M/T method are familiarized technique,But how to get the most simplified circuits is still a problem.This paper puts their practical examples.As for KT method the author more systemetically introduces its principle and circuit.By means of KT the very high accur- acy and minimum calculation can be obtained in wide range.The paper evaluates all the above four methods.
