分析了一种噪声信号处理方法 ,针对颗粒计数仪的单颗粒激光散射信号弱、噪声大的实际情况 ,利用自适应噪声对消原理 ,从掺杂有噪声的混合信号里 ,获取单颗粒的散射光信号 ,以解决噪声抑制问题。
A method of noise signal processing is analyzed. According to the fact that single particle laser scattering signal of particle counter is weak and noisy, single particle scattering is obtained from mixed noise-doped signal by using adaptive noise cancellation principle. Optical signal to solve the noise suppression problem.
