Analog Filters

Analog filters are electronic circuits designed to selectively allow certain frequencies of signals to pass while blocking others. Think of them like a sieve that separates different sizes of particles; in this case, they separate signals based on their frequency. They are used in radios, audio equipment, and communication devices to enhance sound quality, reduce noise, or isolate specific signals. These filters work with continuous electrical signals, unlike digital filters which process discrete data. Overall, analog filters help shape and improve the quality of signals in various electronic systems.
