Uyini umehluko phakathi kwe-IR ne-RF?

I-infrared ifushaniswa ngokuthi i-IR. Luhlobo lwemisebe kagesi enama-wavelength amade kunokukhanya okubonakalayo kodwa amafushane kunamagagasi omsakazo. Ivame ukusetshenziswa ekuxhumaneni okungenantambo ngoba amasignali e-infrared angalethwa futhi amukelwe kalula kusetshenziswa ama-diode e-IR. Isibonelo, i-infrared (IR) isetshenziswa kabanzi ekulawuleni kude imishini kagesi efana namathelevishini nezidlali ze-DVD. Ingasetshenziswa futhi ekufudumaleni, ekomiseni, ekuzweleni, kanye nase-spectroscopy, phakathi kwezinye izinto.

I-Radio Frequency ifushaniswa ngokuthi i-RF. Ibhekisela kububanzi bemvamisa kagesi evame ukusetshenziswa ekuxhumaneni okungenantambo. Lokhu kuhlanganisa imvamisa esukela ku-3 kHz kuya ku-300 GHz. Ngokushintsha imvamisa, ubukhulu, kanye nesigaba segagasi lomthwali, amasignali e-RF angathutha ulwazi ebangeni elikhulu. Izinhlelo eziningi zisebenzisa ubuchwepheshe be-RF, okuhlanganisa ukuxhumana ngocingo, ukusakaza, izinhlelo ze-radar, ukuxhumana ngesathelayithi, kanye nokuxhumana okungenantambo. Ama-transmitter nama-receiver omsakazo, ama-router e-WiFi, omakhalekhukhwini, kanye namagajethi e-GPS konke kuyizibonelo zemishini ye-RF.

Kokubili i-IR (Infrared) kanye ne-RF (Radio Frequency) kusetshenziswa kabanzi ekuxhumaneni okungenantambo, kodwa kunezimo ezithile ezinkulu:
1. Ibanga: I-RF inobubanzi obukhulu kune-infrared. Ama-RF transmissions angadlula ezindongeni, kuyilapho amasignali e-infrared engakwazi.
2. Umugqa wokubona: Ama-transmitter e-infrared adinga umugqa ocacile wokubona phakathi komthumeli kanye nomemukeli, kodwa amasignali emvamisa yomsakazo angageleza ngokusebenzisa izithiyo.
3. Ukuphazamiseka: Ukuphazamiseka okuvela kwamanye amadivayisi angenantambo esifundeni kungathinta amasignali e-RF, yize ukuphazamiseka okuvela kumasignali e-IR kungavamile.
4. I-bandwidth: Ngenxa yokuthi i-RF inomkhawulokudonsa omkhulu kune-IR, ingathwala idatha eningi ngesivinini esisheshayo.
5. Ukusetshenziswa kwamandla: Ngenxa yokuthi i-IR isebenzisa amandla amancane kune-RF, ifaneleka kangcono kumadivayisi aphathekayo njengezilawuli ezikude.

Ngamafuphi, i-IR ingcono kakhulu ekuxhumaneni okufushane, okubonakala ngomugqa wokubona, kanti i-RF ingcono ekuxhumaneni okude, okungena ezinkingeni.

Xhumana nathifuthi singabelana ngolwazi olwengeziwe mayelana nezibani ze-LED strip.
