数字锁相环实现源码，有很大的参考价值。 由 鉴相器 模K加减计数器 脉冲加减电路 同步建立侦察电路 模N分频器 构成.(DPLL realize source, has a great reference value. By the phase detector counter modulus K addition and subtraction circuit synchronous pulse addition and subtraction to establish surveillance mode N divider circuit constituted.)

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.)
