系统干扰信号分析及其抑制措施典例

The example of measure about sistom's interferance signal that being analysed and restrained

干扰在测量中是一种无用信号,为了有效抑制测试过程中的干扰,必须了解干扰来源及传输途径,有针对性地选择抗干扰措施。本文从干扰信号的来源分析入手,以电机性能测试系统中抗干扰电路设计为例,通过软件仿真对信号干扰问题加以研究探讨,以期在各种不同情况下选取最恰当的抗干扰办法,获得最佳抑制效果。

Disturbance is a useless signal in measure. During determination, for to restrain the distrubance, its source and way must be found out and we head choice correct measure for interference rejection. This paper begin with disturbance source, by the aid of example about interference rejection circuit design in generator property testing system, to research the question of interference rejection by software simulator, and select the proper way for it under difference situation, so to get the best effect.
