来自ptbdb数据库的信号的读取，该数据库内ECg信号的格式与传统的MIT-HIT数据库不同，是12导的数据，通过程序读取后，数据保存为Matlab矩阵的形式。(read ECG signal from the ptbdb database. Data form of this database is different from the tranditional "212" formal ECG signal. It returns ECG data of 12-leads in a matrix)

说明：  这是一个costas环的例子，我做了比较详细的说明(This is a costas loop as an example, I have done a more detailed explanation)

进行HHT的EMD分解，经验模态分解算法，(The HHT-EMD decomposition)

making exponential signal with matlab In communications, the purpose of using exponential signals instead of sinosuid ones is to use both halves of signal spectrum(Negative and Positive sides of spectrum). For example an FSK signal can not simply downconverted to DC. because its spectrum is not symmetric around its center frequency, so you should downconvert it with exponential signal( the idea of using I and Q downconverter).
