LC filter is passive components that pass or reject a specific frequency band.
These components are used for extracting the specific frequency band or rejecting for noise reduction.
Low-pass filter: LPF
It passes low frequencies and blocks high frequencies.
High-pass filter: HPF
It passes high frequencies and blocks low frequencies.
Band-pass filter: BPF
A band filter (or band-pass filter) is a filter that only passes signals between specific frequencies.
