- 本次实验是要我们先产生心电信号，再加噪声再滤波。由一个心电信号数据表输出心电信号，由于已知的心电信号有噪声，所以我先将信号进行滤波，得到正确的心电信号。再加噪声，通过滤波可以得到高频和中频噪声，将原信号加上噪声显示再滤波。每次的时域信号都画出了他们相应的频谱，便于观察。每次的滤波我也尝试了不同的滤波器。-This experiment is to produce our first ECG, together with noise and then filtering. ECG data fro

- 用dsp实现自适应滤波器算法，自适应滤波是仅需对当前观察的数据作处理的滤波算法。它能自动调节本身冲激响应的特性，或者说自动调节数字滤波器的系数，以适应信号变化的特性，从而达到最佳滤波。由于自适应滤波不需要关于输入信号的先验知识，计算量小，特别适用于实时处理，近年来得到广泛应用，如用于脑电图和心电图测量、噪声抵消、扩频通信及数字电话等。-Dsp to achieve the adaptive filter algorithm, the adaptive filter is a filter tha

- 基于小波变换的ECG信号去噪系统设计,在信号采集时，身体的任一微小运动都会产生“基线漂移”，这是一种低频干扰，同时，由于肌电的存在又产生了高频的肌电噪声，由于空间电磁场的存在又使心电信号中混有50Hz的工频干扰。这些噪声不去除，就会影响下一步的信号处理。 综合运用数字信号处理的理论知识进行生物医学信号增强系统设计，实现ECG信号的去噪，从而加深对小波变换及其应用的理解，建立概念多分辨分析的概念，加深理解信号增强的原理、方法和步骤。本设计的主要内容是设计一个基于小波变换的ECG信号去噪系统，
