摘　　要：生理信号的特点是信号微弱、频谱宽、数据量少和噪声复杂。数字滤波是处理生理信号的基本手段。提出一种基于小波变换的自适应数字滤波器,以软件的方式实现,并应用于生理信号处理,效果比较理想。The characteristics of the physiological signal are signal weakness, wide frequency, less information and complicated noise. And the digital filter is the basic measure to process the physiological signal. A kind of adaptive digital filter based on wavelet transform was described, and the arithmetic was processed in form of software. At last the arithmetic was used in the physiological signal processing, and, a good result was obtained.
