TPS N(Timing．Sync Portocol for Sensor Networks)黻Ganeriwal等人提出的适用于无线传感器网络整个网络范围内的时间同步算法。该算法分两步：分级和同步。第一步的目的是建立分级的拓扑网络，每个节点有个级别。只有一个节点定为零级，叫做根节点。在第二步，i级节点与i．1级节点同步，最后所有的节点都与根节点同步，从而达到整个网络的时间同步。

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.)
