比特沃思滤波器
Examples
- Design of digital butterworth filter by matlab language
设计巴特沃斯数字滤波器 - State feedback greatly suit pole placement . getting optimized eigenvalue of det [ si - ( a - bk ) ] = 0 is the target of pole placement by selecting state feedback matrix k . the root of state feedback can be placed in term of the form of butterworth filter or bessel filter
极点配置就是选择状态反馈矩阵k ，使系统的本征多项式det [ si - ( a - bk ) ] = 0的本征值处于最适宜的数值上，即获得最优的根配置。 - The design method of the double charge amplifier are worked out based on the requirement of the sensor for testing circuit and the effect of sensor for work environment , the method of compensation of the frequency being extended is studied , and the butterworth filter of five order which is adapted itself is designed creatively by the isppac in chapter three
第三章从敏感元件对测量电路的要求和工作环境的影响出发，提出了双电荷放大器的设计方案，研究了频率拓宽补偿的方法，使用isppac创新设计了自适应butterworth5阶低通滤波器。 - We design the qmf based on the criteria of minimum frequency bandwidth and the qmf that possess linear phase , and give a example of a signal decomposed and restructured . 4 . in the research of channel dropping filters , we use 5 rank butterworth filter to approach the digital filter . we design lc unpower netwok and rc power network . we manufacture lc lowpass and highpass filter ， and test their performance ; we simulate the appliance of the channel dropping filters in the system
4 .在频带分割滤波器的设计方法中，用5阶巴特沃斯滤波器逼近最小频宽正交镜像滤波器，对无源和有源滤波器进行了仿真设计；设计并制作了无源lc低通和高通滤波器，测试了它们的性能；并对分割滤波器在系统中的应用进行了计算机仿真。 - The nucleus is the software in the design and realization of virtual instruments . we use the design method of module and use many papers to describe the whole building process of the typical signal generation module , date handling module , date reading and writing module , resultdemonstrate module . as the conclusions , we also offer the panels and the diagrams of virtual signal frequency spectrum analytical instrument , virtual butterworth filter , virtual signal generation instrument , virtual integrator and differentiator regulator and amplitude modulation wave counter modulation instrument
本文采用模块化设计方法，详细描述了典型信号生成模块、数据处理模块、数据读取和存储模块、显示模块等软件开发的全过程，分析、解决了设计及实现过程中出现的问题，并给出了已实现的虚拟信号频谱分析仪、虚拟巴特沃斯滤波器、调幅波解调器、虚拟信号发生器、虚拟积分器和微分器等实验教学用虚拟仪器的前面板图和程序流程图。
