资料介绍

在进行数字电子产品研制过程中,必然会遇到各种各样的噪声.为了揭示毛刺噪声的根源,通过实验对传输信号中的毛刺噪声波形进行反复比较.采用奇/偶校验器来检测信号传输过程中毛刺噪声是否存在.采用两种主要方法消灭毛刺噪声:(1)应用选通脉冲和“与门”电路来恢复尖峰噪声中的理想脉冲信号.(2)用RC积分电路削弱毛刺噪声.实践中,使用这些措施去抑制数码电子产品的毛刺噪声,都达到了事半功倍的效果.

It is meeted all kinds of noise to design in digital circuits of equipment. In order to reveal the source of the burr noise, the waveform of burr noise is observed and analyzed over experimentals. According to need in the actual, there is the burr noise in the signal on the odd/even validator. The burr noise is prevented through two main ways. ( 1 ) The ideal signal is restored on the strobe and "and". (2) The gate door of burr noise is blocked on the RC integrated circuit in digital electron- ic products. In Practice, the burr noise is suppressed in digital circuits of equipment through these measures. It has reached a multiplier effort.
