Butterworth filter
* vlakke doorlaatkarakteristiek
* gemiddelde dempingsfactor α
* fasekarakteristiek is niet lineair
Chebyshev filter
* doorlaatkarakteristiek daalt sterker dan bij Butterworth
* dempingsfactor is klein (onderkritisch gedempt)
* minder lineaire fasekarakteristiek dan bij Butterworth
Besselfilter
* lineaire fasekarakteristiek
* grote dempingsfactor (bovenkritisch gedempt)
* doorlaatkarakteristiek minder steil
