| 摘 要： | 针对模拟Ｈ－Ｊ电路存在的失调严重影响脉冲信号分离的问题。本文提出了适用于脉冲信号分离的Ｈ－Ｊ模拟实验方法，并采用一种便于ＣＭＯＳ工艺实现的非线性模块使Ｈ－Ｊ网络实现更加简化。Ｓｐｉｃｅ模拟结果表明，该方法能够实现对诸如人体心电信号等脉工信号的盲分离。

| Abstract: | Blind separation of mixed impulse signals with analog H-J network may be severely affected by the intrinsicoffset voltage of analog circuits. In order to solve this problem, a new scheme is adopted, Also a novel nonlinear block isused to simplify the architecture, which can be easily implemented using CMOS technology. Simulation results of SPICEshow that the scheme can successfully separate impulse signals such as electrocardiograms from each other. |
