Butterworth cov ntxaij lim dej yog hu ua cov ntxaij lim dej loj tshaj plaws vim tias, rau qhov kev txiav txim, lawv muaj qhov ntse tshaj plaws yob-tawm yam tsis tau inducing peaking hauv Bode zajlus. Ob-ncej lim nrog damping piv ntawm 0.707 yog qhov thib ob-order Butterworth lim .
Lub lim twg muab cov lus teb ncaj nraim?
Lub Butterworth filter yog hom teeb liab ua lim tsim kom muaj cov lus teb zaus raws li qhov ua tau nyob rau hauv passband. Nws kuj tseem raug hu ua lub lim dej loj tshaj plaws .
Yam twg ntawm cov ntxaij lim dej hauv qab no muaj cov lus teb siab tshaj plaws?
Yam twg ntawm cov ntxaij lim dej hauv qab no muaj cov lus teb siab tshaj plaws? Piav: Q7 .
Lub lim twg muaj qhov siab tshaj plaws?
Lub lim twg muaj qhov siab tshaj plaws? Nqe lus piav qhia: Butter-worth filter raws li qhov kwv yees zoo tshaj plaws rau cov lim dej zoo tshaj plaws thiab muaj qhov siab tshaj plaws nyob rau hauv lub lim pass-band .
Qhov twg ntawm cov ntxaij lim dej hauv qab no muaj cov lus teb tsawg dua monotonically?
Cov lus teb loj ntawm tag nrho-ncej lim xws li Bessel, Butterworth, thiab Chebyshev (hom 1) yog monotonically txo cov haujlwm ntawm zaus hauv qhov nres .
