【摘要】 以支持电解质溶液产生的示波计时电位信号作为线性函数、去极剂本身的示波信号作为去噪函数 ,提出了一种傅里叶自去卷积新方法———示波信号能谱的傅里叶自去卷积法。研究了噪音和切口重叠等对去卷积结果的影响。与其他傅里叶自去卷积法相比较 :该方法具有操作简单、不会引起负的旁瓣效应、不用选择去噪函数等优点更多还原

【Abstract】 A new method of Fourier self-deconvolution (FSD), Fourier self-deconvolution for power spectrum of oscillographic signal, was proposed. In this method, the oscillographic signal of pure base solution and depolarizer was used as line shape function and apodization function, respectively. Effect of noise and overlapped incision caused by the depolarizer on the result of the deconvolution, and the sensitivity of incision after deconvolution was investigated. Compared with classical FSD and other deconvolution methods, Fourier self-deconvolution for power spectrum of oscillographic signal can not only increase the relative incision depth, but also improve the resolution for the overlapped incision and the sensitivity.更多还原
