复合信号的分辨新技术
New Resoluting Method of Compound Signal
【摘要】 将样条小波变换技术用于分辨复合信号, 以选定的分辨因子作用于样条小波滤波器, 使之成为峰分辨器, 用它来直接处理复合信号, 取得了较好的结果, 被处理峰可达到基线分离, 且峰位置的相对误差小于30 % , 峰面积的相对误差小于50 % , 方法简便易行; 讨论了各种影响分峰效果的因素, 包括不同的分辨因子及样条小波基等。并应用于铅 ( Ⅱ) —铊 ( Ⅰ) 体系的处理以验证该方法。
【Abstract】 The application of spline wavelet transform in resolving overlapping voltammetric peaks is proposed for the first time. A suitable resolving factor is chosen to multiply the filters of spline wavelet and make it become peak resolute. Simulating overlapping voltammetric peaks are processed by the peak resolute and get satisfactory results, base line separation can be achieved, the relative errors of peak position are less than 3 0%, and the relative errors of peak area are less than 5 0%. The effect of different resolving factors and spline wavelet basis is discussed. For testing the procedure, lead(Ⅱ) thallium(Ⅰ) system is used.
