抑制电子电路中空间干扰噪声的措施

The Space Noise is Prevented in Space Noise

在进行电子产品开发过程中,必然会遇到各种各样的噪声。为了揭示空间噪声的根源、传输途径及抑制方法,在实验中,反复采用系统接地和电磁屏蔽有效结合的手段,对电路信号中的空间噪声波形进行观察、比较与分析。实践中,使用这些措施去抑制电子产品的空间噪声,都达到了事半功倍的效果。

It is meeted all kinds of noise to design in electrocircuit of equipment, in order to reveal the source and the transmission path and the Suppression method of space noise in electroeircuit, the waveform of space noise is observed and compared and analysised over experimentals. According to need in the actual, the space noise is prevented on two main ways are effective combinated that are system grounding and electromagnetic shielding. In Practice,the space noise is suppressed in quipments through these measures, which has reached a multiplier effort.
