多级RC积分电路的幅频特性研究

黄正洋，电子信息系

摘 要：在近代电信设备和各类控制系统中，滤波器应用极为广泛，滤波器的优

劣直接决定产品的优劣，所以，滤波器的研究和生产历来为各国所重视。我国现有滤波器的种类和所覆盖的频率已基本上满足现有各种电信设备。从整体而言，我国有源滤波器发展比无源滤波器缓慢，尚未大量生产和应用。随着电子工业的发展，对滤波器的性能要求越来越高，功能也越来越多，并且要求它们向集成方向发展。我国滤波器研制和生产与上述要求相差甚远，为缩短这个差距，电子工程和科技人员负有重大的历史责任。利用matlab仿真各种滤波电路的波形，可以直观观察波形和测量RC幅频特性。 关键词：滤波器、幅频、相频

Abstract：In modern telecommunication equipment and various types of control system,the filter application is extremely extensive, so the filter directly determines the quality of product, the research and production of filter , countries has been paid much attention to the filter.Types of filter and the frequency they are covered has been basically meet the existing telecommunications equipment in our country.On the

whole, our active filter's development is slowly than passive filter,not mass production and application.With the development of electronic industry,the requirements and features of the filter gap,electronic engineering and technical personnel has great historic responsibility.By using MATLAB simulation filter circuit waveforms,can directly observe waveform and amplitude frequency characteristic measurement RC.

Key words：Wave filter ;The amplitude frequency; Phase frequency
