Improving Liquid Chromatography-Mass Spectrometry Peak Signals Using Noise Frequency Spectrum Modification between Two Filtering Procedures
碩士 === 國立中正大學 === 化學所 === 95 === Abstract Second derivative filter is one kind of band pass filter. When the signal profile is differentiated twice consecutively, the constant and linear part of the background is eliminated; the result is a rather sharp peak rising above a background around zero.
