Yintoni umahluko phakathi kwe-IR kunye ne-RF?

I-infrared ifinyezwa ngokuthi yi-IR. Luhlobo lwemitha ye-electromagnetic ene-wavelengths ezinde kunokukhanya okubonakalayo kodwa ezimfutshane kune-radio waves. Isetyenziswa rhoqo kunxibelelwano olungenazingcingo kuba imiqondiso ye-infrared inokuhanjiswa kwaye ifunyanwe lula kusetyenziswa ii-IR diodes. Umzekelo, i-infrared (IR) isetyenziswa kakhulu kulawulo olukude lwezixhobo ze-elektroniki ezifana neethelevishini kunye nezidlali zeDVD. Ingasetyenziselwa ukufudumeza, ukomisa, ukuva, kunye ne-spectroscopy, phakathi kwezinye izinto.

I-Radio Frequency ifinyezwa njenge-RF. Ibhekisa kuluhlu lwee-frequency ze-electromagnetic ezisetyenziswa rhoqo kunxibelelwano olungenazingcingo. Oku kuquka ii-frequency eziqala kwi-3 kHz ukuya kwi-300 GHz. Ngokutshintsha i-frequency, ubukhulu, kunye nesigaba se-carrier wave, imiqondiso ye-RF inokuthutha ulwazi kwiindawana ezinkulu. Ii-application ezininzi zisebenzisa itekhnoloji ye-RF, kubandakanya unxibelelwano, usasazo, iinkqubo ze-radar, unxibelelwano lwesathelayithi, kunye nenethiwekhi engenazingcingo. Ii-transmitters kunye nee-receivers zerediyo, ii-routers ze-WiFi, iifowuni eziphathwayo, kunye nezixhobo ze-GPS zonke ziyimizekelo yezixhobo ze-RF.

Zombini i-IR (Infrared) kunye ne-RF (Radio Frequency) zisetyenziswa kakhulu kunxibelelwano olungenazingcingo, kodwa kukho umahluko omkhulu:
1. Uluhlu: I-RF inoluhlu olukhulu kune-infrared. Iitransmissions ze-RF zinokudlula eludongeni, ngelixa imiqondiso ye-infrared ingenako.
2. Umgca wokubona: Iitransmitter ze-infrared zifuna umgca ocacileyo wokubona phakathi kwetransmitter kunye nereceiver, kodwa imiqondiso yerediyo inokugeleza ngokusebenzisa izithintelo.
3. Ukuphazamiseka: Ukuphazamiseka kwezinye izixhobo ezingenazingcingo kulo mmandla kunokuchaphazela imiqondiso yeRF, nangona ukuphazamiseka kwemiqondiso ye-IR kungaqhelekanga.
4. I-bandwidth: Ngenxa yokuba i-RF ine-bandwidth enkulu kune-IR, inokuthwala idatha engaphezulu ngesantya esikhawulezayo.
5. Ukusetyenziswa kwamandla: Ngenxa yokuba i-IR isebenzisa amandla amancinci kune-RF, ilungele ngcono izixhobo eziphathwayo ezifana nezilawuli ezikude.

Ngamafutshane, i-IR ingcono kakhulu kunxibelelwano olufutshane, olusebenzisa umgca wokubona, ngelixa i-RF ingcono kakhulu kunxibelelwano olusebenzisa umgca wokubona olude, olungena kwimiqobo.
