What is meant by filter? What are the different types of filters?
The output of the rectifier pulsating in nature, it consists of a desired DC component of voltage and unwanted ripple components. These ripple components are removed by placing filter circuit at the output of the rectifier.

Types of filters:
1. capacitor filter
2. series inductor filter
3. LC filters of following two types
(a)capacitance input filter
(b)inductance unput filter
4.RC filters.

RE: What is meant by filter? What are the different types of filters?
Filters are used to remove the unwanted or undesirable components of a output
waveform so the basic work of filters is to smoothen the output.
From electrical devices we
are not getting perfect sinusoidal output it contains a DC component i.e.
ripples harmonic distortions etc. so filters are used to rectify these
components.
