Differences between shunt capacitor (C), series inductor (L), chokes input (LC) and π filters.

Following are the difference between shunt capacitor (C), series inductor (L), chokes input (LC) and π filters :

Shunt capacitor (C) filters Series inductor (L) filter Choke input (LC) filter Capacitor input (π type) filter
Only capacitor is used. Only inductor is used. One inductor and one capacitor are used. Two inductors and two capacitors are used.
