Passive Filters

Passive filters are utilized to shape the frequency spectrum of signals across a diverse array of applications. These filters, using only passive elements like resistors (R), inductors (L), and capacitors (C), are capable of selectively allowing or blocking certain frequency ranges without the need for external power sources.

Consider an audio speaker system with filter circuits. These circuits selectively pass desired frequencies while attenuating others, limiting signals to a specific frequency band.

Filters are categorized as passive when exclusively using passive components like resistors, inductors, and capacitors.
