Components involved in filter Circuit. A filter circuit comprises of generally inductor and capacitor. The inductor allows DC only to pass through it and capacitor allows AC only to pass through it. Thus, a circuit formed by the combination of inductors and capacitors can effectively filter the signal according to the application.
Capacitor filters, also known as capacitor-input filters or simply RC filters, are electronic circuits used to filter and smooth electrical signals. They consist of a capacitor (C) and a resistor (R) connected in series or parallel. Here are some of the pros and cons of using capacitor filters: Pros:
A capacitor allows A.C only and an inductor allows D.C only to pass. So a suitable L and C network can effectively filter out the A.C component from the rectified wave. A filter circuit consists of passive circuit elements i.e., inductors, capacitors, resistors, and their combination.
In the inductor filter, the ripple factor is directly proportional to the load resistance. On the other hand in a capacitor filter, it varies inversely with the load resistance. Hence if we combine the inductor filter with the capacitor the ripple factor will become almost independent of the load filter.
The output voltage is less compared to the capacitor filter. An LC filter is a combination of a capacitor and a choke filter with properties of both filters. The choke blocks the AC component and Pass DC. The capacitor bypasses further fluctuations and provides DC across it.
And this capacitor filters out the DC component so that only AC goes through. In the same way that capacitors can act as high-pass filters, to pass high frequencies and block DC, they can act as low-pass filters, to pass DC signals and block AC. Instead of placing the capacitor in series with the component, the capacitor will be placed in parallel.
A filter circuit is a device that is used to remove the A.C components of the rectified output but allows the D.C components to reach the load. A filter circuit is in general a combination of inductor (L) and Capacitor (C) called an LC filter circuit. A capacitor allows A.C only and an inductor allows D.C only to pass.

Through the interconnection of coil and capacitor, a circuit is constructed whose output voltage changes with the frequency of the input voltage.

For some types of filters, the design and damping char-acteristics may need to be maintained to meet specific performance requirements. For many actual line filters, however, a damping factor of approximately 1 or greater and a cutoff frequency within about an octave of the calculated ideal should provide suitable filtering.
A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance.
