resonance filter

Furthermore, new concepts of equivalent PEC wall and equivalent microwave resonance cavity are suggested to analyze the resonance phenomenon and filtering effect. The relationship between the filter structure and the filter center frequency is acquired and a method to calculate this center frequency is proposed.

进一步通过引入等效PEC面与等效微波谐振腔的概念，分析了谐振现象与滤波特性之间的关系，得到了滤波器中心频率与滤波器结构参数的关系式与中心频率的计算方法。

The Highpass resonance Q ( known as Highpass Resonance Quality Factor) determines how much the filter's self-resonance is dampened.

高通共振品质（被称为高通共振品质因数）决定多少滤波器的自共振被抑制。
