IIR 数字滤波器的设计与实现
说明: 设计一个巴特沃兹数字低通滤波器,其技术指标为:3dB带宽为0.2π,阻带截止频率为0.3π,通带纹波为1dB,阻带衰减大于30dB,采样间隔T=10ms。
1)采用冲激响应不变法;
2)采用双线性变换法设计;
3)采用FIR的窗函数(Hanning窗、Hamming窗或Blackman窗)设计。(A Butterworth digital low-pass filter is designed. Its technical specifications are: 3 dB bandwidth is 0.2 pi, stopband cut-off frequency is 0.3 pi, passband ripple is 1 dB, stopband attenuation is more than 30 dB, sampling interval T=10 Ms. 1) Impulse response invariance method is adopted. 2) Design by bilinear transformation method; 3) FIR window function (Hanning window, Hamming window or Blackman window) is used to design.)

COM_customplot
说明: 自己用的小软件,仿造原子的XCOM功能,加了一下自己用的功能。
1、基本串口通讯,鼠标放入串口选择自动刷新,显示COM口的驱动类型。
2、多条发送界面,可定时发送,可关联数字键盘、右键发送按钮可更改按钮名称,方便记忆。
3、485通讯,数据有十进制和十六进制可选,发送后自动保留记录。
4、CRC校验小工具。
5、十六进制通信协议提取部分位并根据自定义数据类型转化为十进制
6、字符格式示波器,例:">P:-1.25",示波器显示曲线名称P,数值-1.25,曲线个数最多8个。
7、类似MODBUS协议截取第2-5位,合成一个int数值,然后示波器显示波形,最多5个曲线
8、示波器曲线可键拖拽、放大(QT serial port assistant, plus digital oscilloscope)
