Emkhakheni omkhulu wokuxhumana nge-elekthronikhi, lapho ukunemba nokuthembeka kubaluleke kakhulu, izixhumi ze-DIN ne-N zigqama njengabaqinile embonini. Lezi zixhumi, nakuba zihlukile ekwakhiweni kwazo nasekusetshenzisweni kwazo, zabelana ngomgomo ofanayo: ukusiza ukudluliswa kwamasignali okungenazihibe kunqwaba yamadivayisi namasistimu. Ake sihlole ubunkimbinkimbi bezixhumi ze-DIN nezi-N, siveze izici zazo, izinhlelo zokusebenza, kanye nokubaluleka kobuchwepheshe besimanje.
Isixhumi se-DIN (Deutsches Institut für Normung), esivela endikimbeni yamazinga yaseJalimane, sihlanganisa umndeni wezixhumi eziyindilinga ezibonakala ngokwakhiwa kwazo okuqinile kanye nomklamo oguquguqukayo. Izixhumi ze-DIN ziza ngosayizi abahlukahlukene kanye nokucushwa, ngasinye sivunyelaniswa nezinhlelo ezithile zokusebenza kusukela kumishini yomsindo/yevidiyo kuya kweyezimboni. Izinhlobonhlobo ezijwayelekile zihlanganisa:
I-DIN 7/16:Isixhumi se-DIN 7/16 yisixhumi se-RF esisebenza kahle kakhulu esivame ukusetshenziswa engqalasizinda yezokuxhumana, ikakhulukazi eziteshini zamaselula kanye nezinhlelo ze-antenna. Inikeza ukudluliselwa okuphansi kokulahlekelwa kwamasiginali e-RF emazingeni aphezulu wamandla, okuyenza ilungele izinhlelo zokusebenza ezifunayo.
Isixhumi esingu-N, esifushane sokuthi “Isixhumi sohlobo lwe-N,” yisixhumi se-RF esiluchungechunge esidume ngokwakhiwa kwaso okuqinile nokusebenza okusezingeni eliphezulu ezinhlelweni zokusebenza zamafrikhwensi aphezulu. Eyasungulwa ekuqaleni ngeminyaka yawo-1940s ngu-Paul Neill no-Carl Concelman, isixhumi se-N selokhu saba isixhumi esibonakalayo esijwayelekile kumasistimu e-RF nama-microwave. Izici ezibalulekile zesixhumi esingu-N zifaka:
1.Ukwakha Okuqinile: Izixhumi ezingu-N zaziwa ngomklamo wazo omazombezombe, ohlanganisa indlela yokuhlanganisa enentambo ehlinzeka ngokukhwelana okuvikelekile futhi evimbela ukunqanyulwa kwengozi. Lokhu kwakhiwa okuqinile kubenza balungele ukufakwa kwangaphandle nasezindaweni ezinokhahlo.
2.Ukulahlekelwa Okuphansi: Izixhumi ezingu-N zinikeza ukulahlekelwa kokufaka okuphansi kanye nokulahlekelwa okukhulu kwembuyiselo, okuqinisekisa ukudluliswa okuphumelelayo kwamasignali e-RF ngokonakaliswa kwesignali okuncane. Lokhu kubenza bafanelekele izinhlelo zokusebenza zemvamisa ephezulu njengokuxhumana kwamaselula, izinhlelo ze-radar, nokuxhumana ngesathelayithi.
I-3.Wide Frequency Range: Izixhumi ezingu-N ziyakwazi ukusebenza phezu kwebanga elibanzi lefrikhwensi, ngokuvamile ukusuka ku-DC kuye ku-11 GHz noma ngaphezulu, kuye ngedizayini ethile nokwakhiwa. Lokhu kuguquguquka kubenza bafanelekele uhla olubanzi lwezinhlelo zokusebenza ezokuxhumana ngocingo, i-aerospace, kanye nezimboni zezokuvikela.
Izicelo Nokubaluleka:
Kokubili izixhumi ze-DIN ne-N zithola ukusetshenziswa okubanzi kuzo zonke izimboni nezinhlelo zokusebenza ezihlukahlukene, ngenxa yokuthembeka kwazo, ukusebenza, kanye nokuhlukahluka. Ezinye izinhlelo zokusebenza ezijwayelekile zifaka:
- Ezokuxhumana: Izixhumi ezingu-N zisetshenziswa kakhulu eziteshini zamaselula, izimpondo, nezinhlelo eziphindaphindayo ze-RF, kuyilapho izixhumi ze-DIN zivame ukutholakala kumishini yezokuxhumana njengamamodemu, amarutha, namasistimu e-PBX.
- Ukusakaza kanye Nomsindo/Ividiyo: Izixhumi ze-DIN zidumile emishinini yomsindo/yevidiyo yokuxhuma amadivayisi afana nezidlali ze-DVD, ama-TV, nezipikha, kuyilapho izixhumi ezingu-N zisetshenziswa emishinini yokusakaza, okuhlanganisa imibhoshongo yokudlulisela kanye nezitsha zesathelayithi.
- I-Industrial Automation: Izixhumi ze-DIN zigcwele emishinini yezimboni nezinhlelo ezizenzakalelayo zokuxhuma izinzwa, ama-actuator, namadivayisi okulawula, okuqinisekisa ukuxhumana nokusebenza okungenazihibe.
- I-RF ne-Microwave Systems: Zombili izixhumi ze-DIN ne-N ziyizingxenye ezibalulekile ezinhlelweni ze-RF ne-microwave, okuhlanganisa imishini yokuhlola neyokulinganisa, amasistimu e-radar, nezixhumanisi ze-microwave, lapho ukudluliswa kwesignali okuthembekile kubalulekile.
Sengiphetha, izixhumi ze-DIN ne-N zimelela izingxenye ezibalulekile endaweni enkulu yezinto zikagesi zesimanje, ezisebenza njengezindawo ezithembekile zokuxhumanisa amadivaysi, amasiginali okudlulisa, nokwenza ukuxhumana okungenazihibe kuzo zonke izinhlelo zokusebenza nezimboni ezihlukahlukene. Njengoba ubuchwepheshe buqhubeka buthuthuka, ukubaluleka kwalezi zixhumi kuzokhula kuphela, kugcizelele ukuhambisana kwazo okuhlala njalo emhlabeni oguqukayo wokuxhumana ngogesi.
