Passive Filters

  • Lars Wanhammar
Chapter

The transfer functions that were discussed in Chapter 2 can be realized with so-called LC filters, or more correctly RLC filters, where RLC refer to resistors, inductors, and capacitors. Such filters are normally realized with only passive elements and are implemented with resistors, coils, and capacitors. A passive or lossless circuit element cannot increase the signal energy. Passive LC filters belong to the oldest implementation technologies but still play an important role as they are being used in large volumes and are used as prototypes for the design of advanced frequency selective filters.
