Bessel带通滤波器在调制系统中的设计与应用

Design and Application of Bessel Pass-band Filter in Modulation System

本文介绍了调制系统中LC带通滤波器的设计与应用。通过对Bessel函数的选取，可实现带内信号线性相位传输，同时实现较高带外幅频抑制度，就LC滤波器与SAW带通滤波器进行了比较。

This paper introduces the design and application of LC pass-band filter in modulation system. By choosing the Bessel function, the filter can realize in-band signal linear transmission, while realize higher out-band amplitude restriction. A comparison between LC filter and SAW pass-band filter is also given.
