Lab0304-XINT
- 在心电信号的采集过程中，会引入各种干扰噪声，如基线漂移。为了得到不失真的心电信号，在诊断分析前要对信号进行预处理---数字滤波。 FIR滤波器容易实现线性相位。对于相位要求严格的场合，要求用FIR滤波器实现滤波，实验要求用用FIR高通滤波器法去除其中基线漂移。 -ECG acquisition process, will introduce all kinds of interference noise, such as baseline drift. In order to get u
matlab
- 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
Lab0505-FIRLMS
- 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
