压电滤波器

[中文适用范围]： 描述作为基本滤波器元件的压电陶瓷谐振器的主要特征及其适用于各种频率范围的参数。处理陶瓷滤波器（梯式、桥式和压电变压器式）电路，并给出不同滤波器类型的电气特性。本出版物修订后将作为 IEC 368-2 发布。 [外文原描述]： Describes the principal features of piezoelectric ceramic resonators, which are basic filter elements, and their parameters applicable to various frequency ranges. Deals with circuits of ceramic filters (ladder, bridge and piezo-electric transformer type) and gives electrical characteristics of different filter types. This publication, when revised, will be issued as IEC 368-2.
