导言电生理记录常常由于噪声干扰而失真,它影响正确的信号分析。例如在心电图中,60Hz的电源噪声可以淹没P、QRS、T波,使得观察或计算机辅助分析的波幅、波长的测量无法进行。因此专用一体化的可选择性地消噪滤波器成为生物医学信号处理系统中重要的一部分。事实上,对于计算机辅助的ECG分析。一个合适的电源噪声滤波处理被认为是计算机程序系统中标淮不可缺少的部分。
Introduction Electrophysiological recordings are often distorted by noise disturbances that affect the correct signal analysis. For example, in the electrocardiogram, 60Hz power supply noise can submerge P, QRS, T wave, making observation or computer-aided analysis of the amplitude, wavelength measurement can not be carried out. Therefore, the special integrated de-noise filter can be an important part of the biomedical signal processing system. In fact, for computer-aided ECG analysis. A suitable power noise filtering is considered an integral part of the standard in computer program systems.
