分光度计的算法及系统构成

Arithmetic and sys constitution of spectrometry

分光度计的峰值求导数是分光度计测量的重要组成部分。模拟式分光度计都不具备此项功能。噪声求导数影响相当大。开发的本系统采用IIR数字滤波器较好的解决了这个问题。本文着重介绍了一个简洁有效的分光度计测量系统及其算法。硬件采用新芯片ADμc81 2构成的ISA插卡系统 ,算法采用双线性变换法。

It is the importment part of spectrometry measure to differentiate wi th respect to wave. All the analog spectrometry don't have this function.Noise with high frequence will do harm to differentitation. This system solves it perf e ctly.The aticle introduces a simple and high efficiency system and its arimetic. Hardware is the new chip ADμc812 making up of a sock system. Arimetic is bilin ear transform,which deal with noise effectively.
