说明：  基于MATLAB的FIR带阻数字滤波器的设计 由于生物医学信号处理过程中易混入50Hz噪声的特点，本文利用程序设计法和FDATool设计法，设 计一带阻滤波器，并将设计的滤波器应用到一混和正弦信号，通过测试检验，该滤波器可以很好地消除50Hz的工 频干扰。(】To prevent the biomedical signals from being disturbed by 50Hz noise easily，the paper designs a bandstop digital filter by procedure and FDATool method．The filter is tested by a blended 81ne wave experimentally and the result shows that the filter can cancel the 50Hz noise very well．)

数据处理及误差分析采用了matlab软件来实现，它的界面虽然没有VB等直观简便，但其可调用的函数多，实现起来比较方便，程序中已经实现的功能有： （1）求算术平均值； （2）求残余误差（绝对误差）； （3）求标准差； （4）判断粗大误差，如果发现粗大误差,剔除粗大误差后再进行计算； （5）判断数据是否具有线性误差或者周期性误差。 (Data processing and error analysis using matlab software to achieve, its intuitive interface, while not VB so simple, but its function can be called many realize it was easier, the program has been implemented features are: (1) Find the arithmetic mean (2) Find the residual error (absolute error) (3) Find the standard deviation (4) to determine gross error, if found to gross error, calculated after excluding gross error (5) to determine whether data has linear error or Periodic error.)
