digital filters
Electronic frequency selectors
Digital filters are algorithms or circuits that process signals to remove unwanted components or extract desired features.
Unlike analog filters that use physical components, digital filters manipulate numerical data—cleaning up audio recordings, sharpening images, or isolating frequencies in electronic signals.
The software applies digital filters to reduce background noise.
