c8_PSDexample
这个例子里，我们将独立(白噪声)样本通过有5dB通带纹波的切比雪夫滤波器。
试估计滤波器输出端的PSD。实现这一估计的MATLAB程序如下:
(This example, we will be independent (white noise) samples through a 5dB passband ripple Chebyshev filter. Estimate the filter output PSD. MATLAB program to achieve this estimate is as follows:)

Regularity_Rythm
After we calculate the R peaks of the ecg signal, we identify different
criteria :
a) Heart rate.
b) Regularity of the R-R peaks (Look at the R-R distances).
1. Regular (are they equidistant apart).
2. Irregular.
c) Rhythm
1. Tachycardia ==> Fast.
2. Bradychardia ==> Slow.
3. Normal.
