Kawm Txog Band Stop Filter


Lim 1

CovBand nres lim, (BSF) yog lwm hom zaus xaiv Circuit Court uas ua haujlwm raws nraim txoj kev rov qab mus rau Band Pass Lim peb saib ua ntej. Lub band nres lim, tseem hu ua band tsis kam lim, hla txhua zaus nrog kev zam ntawm cov nyob rau hauv ib qho kev txwv nres band uas yog heev attenuated.

Yog tias qhov chaw nres tsheb no nqaim heev thiab muaj kev cuam tshuam ntau dua li ob peb lub hertz, tom qab ntawd lub band nres lim feem ntau hu ua lub lim dej, raws li nws cov lus teb zaus qhia tau hais tias ntawm qhov sib sib zog nqus thais nrog kev xaiv siab (seep-sab nkhaus) es tsis yog ib txoj kab dav dav.

Tsis tas li ntawd, ib yam li lub lim lim, lub band nres (band reject or notch) filter is a second-order (ob-pole) filter with two cut-off frequencies, commonly known as the -3dB or half-power point made a wide stop bandwidth of these ob -3dB point.

Tom qab ntawd qhov kev ua haujlwm ntawm lub band nres lim dhau dhau tag nrho cov zaus ntawm xoom (DC) mus txog rau nws thawj (qis) ntu ​​ntu ntu ntu ƒL, thiab dhau tag nrho cov zaus tshaj nws qhov thib ob (sab sauv) txiav tawm zaus ƒH, tab sis thaiv lossis tsis lees txais tag nrho cov zaus hauv nruab nrab. Tom qab ntawd cov lim bandwidth, BW txhais tau tias: (ƒH - ƒL).

Yog li rau qhov dav-band band nres lim, cov ntxaij lim dej tiag tiag nres band nyob nruab nrab ntawm nws qis thiab sab sauv -3dB cov ntsiab lus raws li nws attenuates, los yog tsis lees txais ib qho zaus ntawm ob qhov kev txiav tawm no. Cov lus teb zaus nkhaus ntawm qhov zoo tagnrho band nres lim yog li muab.

Qhov zoo tagnrhoband nres limyuav muaj infinite attenuation nyob rau hauv nws nres band thiab xoom attenuation nyob rau hauv ib tug pass band. Kev hloov pauv ntawm ob qhov hla dhau thiab qhov nres nres yuav yog ntsug (cib ntsa). Muaj ntau txoj hauv kev uas peb tuaj yeem tsim "Band Stop Filter", thiab lawv txhua tus ua tiav tib lub hom phiaj.
