Filtra Transitus Humilis RF Coaxialis Altae Frequentiae Microstrip Microundarum Undae Millimetricae Radiofrequentiae Lineae Suspensae Stripline Ductus Undarum
Filtrum RF transiens infra limites est filtrum ad signa tractanda quod signa infra limites conservat, signa infra limites removendo. Signa cum frequentiis infra certum limen transire permittit, sed signa cum frequentiis supra illum limen rejicit.
Proprietates filtrorum frequentiae radiophonicae inferioris transeuntis:
1. Sola signa infra certam frequentiam transire permittuntur, dum signa supra illam frequentiam filtrantur vel debilitatur.
2. Cum per signa humilis frequentiae transeunt, nulla fere mutatio phasis fit.
3. Solet fieri ut unus vel plures condensatores et inductores ad filtra infra limites telecommunicationis construenda adhibeantur.
Usus filtrorum coaxialium transeuntis humilis:
1. Signum lene
Filtrum frequentiae altae et frequentiae humilis (IM) praecipue ad signum leniendum adhibetur, strepitum in signo frequentiae altae removere potest, ita ut signum stabilius fiat. Si signum leniter requiritur, filtrum microstrip IM strepitum interferentiae frequentiae altae removere potest, ita systema certius et stabilius reddens.
2. Reductio sonitus
Filtrum frequentiae humilis (vel "low pass filter") signum frequentiae humilis non afficit; dum signum frequentiae humilis retinet, strepitus frequentiae altae excludi potest. In processu audio vel imaginum, filtra frequentiae humilis strepitum excludere et signum processum clarius reddere possunt.
3. Errorem minue
Filtrum infra frequentias (vel "low pass filter") errorem minuere potest, praesertim aptum ad mensuras instrumentorum accuratas. In quibusdam mensuris difficilibus, filtrum infra frequentias strepitum, impedimenta, et alia elementa removere potest, ut mensurae eventus accuratiores et certiores sint.
4. Lata applicationis varietas
Filtrum millimetricum transiens applicationum latissimam habet varietatem, ab audio ad imaginem, a communicatione ad imperium, fere ubique. Exempli gratia, in processu signorum baseband, filtrum parvae magnitudinis transiens necessarium est.
In communicatione, filtrum suspensum frequentiae humilis strepitum altae frequentiae, interferentiam, cetera excludere potest, ut qualitas communicationis confirmetur; in campo moderationis, filtrum stripline ad leniendum signum et filtrandum strepitum adhiberi potest.
QualwaveFiltra microfluctuum infra frequentias in ambitu DC-50GHz suppeditat. Filtra infra frequentias ductuum undarum late in multis applicationibus adhibentur.
