Synonyms: LPF low-pass-filters

Subtag of filter

A low-pass filter (LPF) is a filter whose pass-band extends from 0Hz to a given cut-off frequency.

A signal applied to the input of an LPF is processed so that all its frequency components below the cut-off will pass through unaltered (ideally), whereas all components with higher frequency will be rejected (ideally).

Q&A How to design a low-pass filter when certain conditions must be met

I am designing a low-pass filter with cut-off frequency = 100Hz and after the cutoff frequency from -3dB to -10dB the average decrease in db/Hz = -0.1 db/Hz.I know how to design a low-pass filter ...
