| 摘 要： | 本文采用状态变量法来综合有源滤波器,它模拟标准二阶传输函数构成二阶带通状态变量滤波器,用这种滤波器作为基本节电路,构成四阶带通、参差调谐四阶带通和参差调谐六阶带通滤波器。研究构成高阶带通滤波器的几种新颖方法。这类带通滤波器时于低频、基低频、高 Q 值和良好的矩形因数等场合是很有用的。

| Abstract: | This paper presents a synthesis-technique of active fihcrs by applicating the method of the state variable.It Simulates the normalized second-order transfer function to the second-order bandpass filter of the state variable.Using that filter makes basie sections,forms the fourth-order bandpass circuit,stagger tuned oircuits of the fourth-order bandpass and the sixth-order bandpass filters. These filters are very useful where frequencies are lower,very low;the quality factor Q is very high and the squareness factor is very good. |
