| 摘 要： | 一个测试系统中,有很多部分组成.其中信号的处理也是重要的一部分.从前级运放输出的电压信号中,不可避免地混杂有噪声和干扰信号.为保证测量的准确性,在进行A/D转换前,必须采取抗干扰和抑制噪声措施以及对信号进行滤波,消除混杂在前级输出中的干扰和噪声1].本文针对在氨氮测定中的采样信号的处理方法进行分析研究,希望通过滤波处理可以在最大程度上消除信号的干扰.

| Abstract: | A test system is composed by many parts.And signal processing is also an important part.For the guarantee surveys accuracy,before carrying on A/D transformation,must adopt the antijamming and the noise elimination measure as well as carries on the filter to the signal, eliminated promiscuously in the level output disturbance and noise.This article in view of con- ducts the analytical study in the ammonia nitrogen determination sampled signal processing method,hoped that through filter processing can elimina... |
