Ukadaulo wamawayilesi opanda zingwe: kusanthula mfundo komanso kugwiritsa ntchito magawo ambiri

RF (Radio Frequency) imatanthawuza mafunde a electromagnetic okhala ndi ma frequency pakati pa 3kHz ndi 300GHz, omwe amatenga gawo lalikulu pakulankhulana, radar, chithandizo chamankhwala, kuyang'anira mafakitale ndi magawo ena.

Mfundo zoyambirira za mawailesi pafupipafupi

Ma siginecha a RF amapangidwa ndi ma oscillator, ndipo mafunde amagetsi othamanga kwambiri amatumizidwa ndikufalitsidwa kudzera mu tinyanga. Mitundu yodziwika bwino ya tinyanga timaphatikiza tinyanga ta dipole, tinyanga ta nyanga ndi tinyanga tating'onoting'ono, tomwe ndi oyenera zochitika zosiyanasiyana zogwiritsira ntchito. Mapeto olandirira amabwezeretsa chizindikiro cha RF kuzidziwitso zogwiritsidwa ntchito kudzera pa demodulator kuti zitheke kufalitsa zidziwitso.

Gulu ndi njira zosinthira ma frequency a radio

Malinga ndi ma frequency, ma frequency a radio amatha kugawidwa kukhala otsika (monga kuyankhulana pawayilesi), ma frequency apakati (monga kulumikizana ndi mafoni), komanso ma frequency apamwamba (monga radar ndi chithandizo chamankhwala). Njira zosinthira zikuphatikizapo AM (pakutumiza kotsika kwambiri), FM (kutumiza kwapakatikati) ndi PM (yotumiza mwachangu kwambiri).

RFID: luso pachimake cha chizindikiritso wanzeru

RFID (radio frequency identification) amagwiritsa ntchito mafunde a electromagnetic ndi ma microchips kuti adzizindikiritse okha, ndipo amagwiritsidwa ntchito kwambiri potsimikizira kuti ndi ndani, kasamalidwe kazinthu, ulimi ndi kuweta nyama, kulipira zoyendera ndi zina. Ngakhale ukadaulo wa RFID umakumana ndi zovuta monga mtengo ndi kuyimitsidwa, kumasuka kwake komanso kuchita bwino kwalimbikitsa chitukuko cha kasamalidwe kanzeru.

Kugwiritsa ntchito kwambiri ukadaulo wa RF

Ukadaulo wa RF umawala m'magawo olumikizirana opanda zingwe, kulumikizana kwa satellite, kuzindikira kwa radar, kuzindikira zachipatala komanso kuwongolera mafakitale. Kuchokera pa ma netiweki a WLAN kupita ku ma electrocardiographs, kuchokera kunkhondo kupita ku mafakitale anzeru, ukadaulo wa RF ukulimbikitsa kupita patsogolo kwaukadaulo ndikusintha moyo wathu.

Ngakhale teknoloji ya RF ikukumanabe ndi zovuta, ndi chitukuko cha sayansi ndi luso lamakono, idzapitirizabe kudutsa zatsopano ndikubweretsa mwayi wambiri wamtsogolo!
