What Is a Band Reject Filter?
A band reject filter (BRF) is designed to obstruct certain frequency bands while permitting the passage of others.
This filter's functionality is based on two primary mechanisms: LC resonance circuits and digital signal processing. In LC resonance circuits, resonance at particular frequencies leads to their attenuation. Conversely, digital signal processing methodologically weakens specific frequency bands.
Band reject filters are instrumental in diminishing noise in audio systems, eradicating interference in communication apparatus, and excluding undesirable frequencies in medical instruments. They serve a crucial role in industrial and measurement devices for signal refinement and noise suppression. Attributes of BRFs include the exclusion of particular frequency ranges, enhancement of noise reduction, amplification of desired frequency bands, compact and lightweight construction, and economic viability.
