Description: 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 from a table output ECG, ECG as a known noise signal is filtered first, I get the correct ECG. Plus noise can be obtained by filtering high-frequency and intermediate frequency noise, the original signal plus noise shown again filtering. Time-domain signals each draw their corresponding spectrum, easy to observe. Every time I try to filter the different filters.

Description: 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 that only the current observation data processing algorithm. It can automatically adjust itself to the impulse response characteristics, or automatically adjust the digital filter coefficients to adapt to the characteristics of the signal changes to achieve the best filter. Adaptive filter does not require a priori knowledge about the input signal, the small amount of calculation, especially real-time processing has been widely used in recent years, such as EEG and ECG measurement, noise cancellation, spread spectrum communications, and digital telephone .
