Bandpass Filters

Band-pass sefa kana bandpass sefa (BPF) chishandiso chinopfuudza mafrequency mukati meimwe tambo uye kuramba (attenuates) frequencies kunze kweiyo tambo.
Bandpass mafirita anoshandiswa zvakanyanya mumadhiraivha asina waya uye vanogamuchira. Basa guru resefa yakadaro mune inotapurirana ndeyekudzikamisa bandwidth yechiratidzo chekubuda kune bhendi rakagoverwa kutapurirana. Izvi zvinodzivirira transmitter kubva kuvhiringa zvimwe zviteshi. Mune inogamuchira, bhendi sefa inobvumira masaini mukati meiyo yakasarudzwa siyana yemafrequency kuti anzwike kana kudhindwa, uku ichidzivirira masaini paasingadiwi mafambiro kubva. Masignals pama frequency ari kunze kwebhendi iyo anogamuchira anotariswa, anogona kuguta kana kukuvadza anogamuchira. Pamusoro pezvo ivo vanogona kugadzira zvisingadiwe zvekusanganisa zvigadzirwa zvinowira mubhendi uye zvinokanganisa chiratidzo chekufarira. Wideband vanogamuchira vanonyanya kukanganiswa kukanganiswa kwakadaro.[3] Bandpass sefa zvakare inokwidziridza chiratidzo-kune-ruzha reshiyo uye kunzwa kweanogamuchira.

Muzvese zviri zviviri kutumira nekugashira maapplication, akagadzirwa zvakanaka bandpass mafirita, ane optimum bandwidth yemodhi uye nekumhanyisa kwekutaurirana kuri kushandiswa, wedzera huwandu hwemasaini ekutumira anogona kuvepo muhurongwa, uku achideredza kupindira kana kukwikwidza pakati pezviratidzo.

Kunze kwemagetsi nekugadzirisa zviratidzo, mumwe muenzaniso wekushandiswa kwebhandi-pass mafirita ari mumhepo yesayenzi. Zvakajairika kuti bhendi-pass sefa ichangoburwa meteorological data ine nguva yenguva, semuenzaniso, mazuva matatu kusvika gumi, kuitira kuti madutu chete arambe achichinja-chinja muminda yedata.
