Two parameters are used to specify the characteristics of a BPF: passband centre frequency and resonancebandwidth.
带通滤波器的特性通过两个参数表示：带通中心频率和共鸣带宽。

In this paper, Finite Element Method (FEM) is applied to the dynamical analysis on a three-axis turntable and a resonance model is built for bandwidth design purpose.
本文用有限元方法对三轴转台控制对象进行动力学分析，建立机械谐振的频域模型，为带宽设计提供了依据。

Secondly, we analyze the even-mode and odd-mode resonance frequency of dual-mode T-shaped resonator and its application in filter bandwidth design.
