Filter is an electronic component used for signal processing. Its main function is to allow signals within a specific frequency range to pass while suppressing or attenuating unwanted frequency components, thereby ensuring signal purity and quality. Filters are widely used in wireless communications, radar systems, and other applications for signal selection and interference suppression.
