Inkcazo ye-Q Factor

I-Q factor ichazwa njengomlinganiselo we-center frequency (f₀) kwi-bandwidth (BW) yesihluzi:
Q = f₀ / BW
Ixabiso eliphezulu le-Q libonisa i-bandwidth encinci kunye nokukhetha okungcono, oko kuthetha ukuba isihluzi sinokukhetha ngokuchanekileyo uluhlu oluthile lwefrikhwensi ngelixa silahla ezinye.

Izicelo Ezisebenzayo kunye NeeNgcebiso

Kwizicelo ezisebenzayo, ukukhethwa kwe-Q factor kuxhomekeke kwiimfuno ezithile. Umzekelo, kwiinkqubo zonxibelelwano ezifuna ukukhetha okuphezulu kunye nokulahleka okuphantsi kokufakwa,izihluzi ze-high-Qzikhethwa nangona zinobunzima obukhulu boyilo kunye neemfuno zamacandelo. Kwiimeko ezinjalo, iingenelo zezihluzi ze-high-Q ngokubhekiselele ekusebenzeni zihlala zingaphezulu kuneengxaki zobomi obunokubakho. Ngokwahlukileyo koko, kwizicelo apho iimfuno ze-bandwidth zingangqongqo kangako, izihluzi ze-low-Q zinokuba lukhetho olungcono ngenxa yobulula bazo, iindleko eziphantsi, kunye nobomi obude.

Isishwankathelo

I-Q factor yesihluzo ichaphazela kakhulu ubomi baso. Izihluzo ze-High-Q, nangona zibonelela ngokusebenza okuphezulu, zifuna izinto ezisemgangathweni ophezulu kunye neenkqubo zokuvelisa ezichanekileyo. Ukuba ezi meko ziyafezekiswa, zinokufikelela kwixesha elide lobomi. Nangona kunjalo, ulwakhiwo lwazo oluntsonkothileyo kunye novakalelo oluphezulu kwiingcinezelo zoomatshini kunye nobushushu zinokubangela imingeni. Izihluzo ze-Low-Q, ezinesakhiwo sazo esilula kunye noxinzelelo oluphantsi lwezinto, zihlala zinexesha elide lobomi kodwa zinokuncama ukusebenza okuthile. Kwizicelo ezisebenzayo, abayili kufuneka balinganise i-Q factor neemfuno ezithile ukuze baphucule ubomi kunye nokusebenza kwesihluzo.
