Description: 1.编码：程序首先提取一个系统时间，取正弦函数值后，对其进行编码，每秒抽样8000次。
每次运行生成8000个值，放入Excel文件中，每次生成一个文件，文件名按数字顺序排列，如文件组有空缺，则生成文件插入空缺位置，并在文件名之后加X以示区别。
例：只有文件x000.xls , x002.xls， 则运行程序后生成x001x.xls
若已有文件x000.xls , x001.xls , x002.xls , ……
X019.xls 共20个文件，则运行后生成x020.xls。
2．解码：运行程序后要求输入想要解码的文件名，则对那文件中的数据进行解码，解码生成的文件名是在文件名前加上recoder_，例如，编码文件：x005.xls，则解码文件名为
redoer_x005.xls。
-PCM codec description of the procedures:
1. Coding: a systematic extraction procedure first time, check sine function value, its encoding, the sample 8000 times per second.
Each run to generate 8000 values into Excel file, each generate a file, the file name in numerical order, such as the file group has vacancies, then inserted into the vacancy position to generate documents, and after the file name to show the difference between X .
Example: Only documents x000.xls, x002.xls, then run the program generated x001x.xls
If there is such a document x000.xls, x001.xls, x002.xls, ... ...
X019.xls a total of 20 documents, while running to generate x020.xls.
2. Decoding: After running the program for the importation of want to decode the file name, then on that document, the data decoder, decoding the generated file name in the file name are added before recoder_, for example, encoded documents: x005.xls, then decode the file name for
redoer_x005.xls.
