Crystal filter is a crystal resonator filter.
Classification of Crystal Filter
Discrete crystal filters, that is, discrete crystal resonators and discrete electronic components constitute the filter.Integrated crystal filters, that is fabricated using integrated circuit technology crystal filters, which is divided into single-chip, single-chip and multi-chip series of three types.
Application of Crystal Filter
The first crystal filters used in telephone communications; now, it is widely used in communications receiver IF selection and single-sideband system. All in all, the crystal filter has been widely used in a variety of electronic devices in the fields of navigation, fire control systems, instruments, and communications.
