摘要
此次电子技术课程设计包括数电课设和模电课设两部分,需要自己独立地完成设计、Multisim仿真和硬件连接三个环节。 模拟电路设计:二阶有源带通滤波器,二阶有源带通滤波器采用经典的RC有源滤波器设计,该设计又称为巴特沃斯滤波器。电路为双电源供电,可完成对于规定中心频率的选择,并保证信号在3db带宽内平稳不失真,且有良好的矩形系数。两个实验均通过了仿真测试和硬件连接测试,基本符合课设的要求。以下是我对两个实验的基本方案、设计原理、元器件的选择、优缺点的比较和仿真结果的介绍。 关键词
带通滤波器、Multisim仿真
Abstract
The course design by the digital circuit design and analog circuit design composed of,360历史Complete independence to complete the design, Multisim simulation and the experiment three links。
Analog circuit design part, second-order active bandpass filter, and through Multisim software and oscilloscope simulation and performance testing,The output resistor, the center frequency coefficient matrix circuit conditions and performance up to requirements. Two experiments were tested by simulation and laboratory simulation tests, the basic compliance testing requirements. This article describes the Responder and the second-order active band-pass filter and the basic program design principles, component selection, compare the advantages and disadvantages and simulation test results, more comprehensive about the design of this course the content of electronic technology.
