本程序是一个设计FIR低通滤波器的程序，用户可以自行输入滤波器的指标以及可以选择6中窗函数，程序将会输出滤波器的参数-This program is a design FIR low-pass filter program, users can enter their own filter indicator window function can select 6, the program will output filter parameters

实现各种滤波器的功能，C++编写的程序,功能丰富，界面漂亮-Achieve a variety of filter functions, C++ programs written

vc6.0编写的iir高通滤波器，可以读取wav文件，显示输入波形和频谱，以及高通滤波后的波形和频谱。还包含有滤波器的验证。-iir vc6.0 prepared by a high-pass filter, you can read wav file, display the input waveform and spectrum, and high-pass filtered waveform and spectrum. Further comprising filter verificat

用VC6.0编写的对话框程序，可以读取ECG（txt格式）数据，并画图。采用差分阈值法对心电信号进行R波的检测并显示R波检测的个数，效果较好。程序中也编写了一个滤波器对心电数据进行滤波。-VC6.0 prepared by the dialog box procedure, you can read ECG (txt format) data, and drawing. Differential threshold method ECG R-wave detect and display the
