有用脉冲中干扰脉冲的去除方法

How to Remove Disturbing Pulses from Useful Pulses

在使用计算机对外部脉冲进行计数的过程中 ,由于干扰脉冲的存在 ,计算机得到的脉冲数往往比实际的脉冲数要多 .为了得到脉冲的准确数值 ,必须想办法把干扰脉冲去掉 .本文介绍了从硬件和软件两方面去掉干扰脉冲的方法 .

When we use computer to count the number of external pulse,because of disturbing pulses the number of pulses that computer receives is bigger than its actual number. To capture the definite number of pulses,disturbing pulses must be removed. The paper introduces the hardware method and software method to remove disturbing pulses.
