陶瓷滤波器是在收音机、录像机、电视机等电子设备中广泛应用的一种特殊器件。它具有无需调整、性能稳定、价格便宜、使用方便等优点,从而广泛用于取代传统的LC滤波网络。其工作原理是利用电压陶瓷的压电效应,将输入的电信号转换成机械振动,机械振动从输入端传递到输出端,并在输出端再转换成电磁振动 Ceramic filter is a special device that is widely used in radio, VCR, TV and other electronic equipment. It has no adjustment, stable performance, low price, easy to use, etc., which are widely used to replace the traditional LC filter network. Its working principle is the use of piezoelectric ceramic voltage effect, the input electrical signals into mechanical vibration, mechanical vibration transmitted from the input to the output, and then converted into electromagnetic vibration output
