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-Based on the MATLAB FIR digital filters with resistance of biomedical signal processing design due process characteristics of noise, with isolator using the program design method a

1． 窗口法设计FIR数字滤波器 2． 以Butterworth 模拟低通滤波器为原型，设计IIR数字滤波器-1. Window design FIR digital filter 2. Butterworth low-pass filter to simulate the prototype, design IIR digital filter

实现了Fir汉宁窗设计II型数字低通滤波器，文件中含有子函数文件，运行成功，无错误-The Fir Hanning window design II digital low-pass filter, the file contains sub function files, run successfully, no error
