毛细管气相色谱信号的小波滤噪
Wavelet De-noising to Process Gas Capillary Chromatography Signals
【摘要】 通过对色谱仿真信号的小波处理,研究了不同色谱峰形的小波变换,提出了基于阈值的毛细管气相色谱信号的小波滤噪方案,改善了色谱信号进行小波高低频分解方法的滤噪性能.
【Abstract】 The wavelet transform of simulate chromatography signals with different chromatography peaks is studied and the de-noising method based on threshold to capillary gas chromatography signals is introduced. The performance of wavelet de-noising is improved here.
