Incazelo: Umqhubi wesifundo osongelwe ngumqhubi ngaphandle ubizwa ngokuthi yi-wire evikelekile. Umqhubi osontekile ubizwa ngokuthi ungqimba lwe-Shieveling, okuvame ukufakwa yi-mesh noma i-foil yethusi (i-aluminium). Isendlalelo sokuvikela kudingeka ukuthi sibekwe esisekelweni, futhi amasiginali angaphandle angenayo angethulwa emhlabathini ngaleli pheya.

Umsebenzi: Vikela amasiginali wokuphazamisa ekungeneni ungqimba lwangaphakathi, kanye nokungenelela komqhubi ngenkathi kunciphisa ukulahleka kwezimpawu zokuhambisa.
Isakhiwo: (Ejwayelekile) ungqimba olufakwayo + ungqimba oluvikayo + umqhubi wesifundo
(Kuthuthukile) ungqimba olufakwayo + ungqimba + wesigilisi wesiginali + ukuvikela umqhubi wesisekelo
Qaphela: Lapho ukhetha ucingo oluvikelwe, umqhubi wesisekelo wokuvikelwa ungqimba wesendlalelo sokufakelwa komqhubi wesisekelo sokuvikelwa komqhubisi unesifiso somsebenzi futhi ungaxhunyaniswa kungqimba lokuvikela (ngokumelana okuthile)

Umsebenzi wokuvikela ucingo ukuhlukanisa umthombo womsindo we-electromagnetic kusuka kumishini ebucayi futhi usike indlela yokusakazeka yomthombo womsindo. I-Shielding ihlukaniswe yaba ukuvimba okusebenzayo nokuvikelwa kokuqina. Inhloso yokuvikela okusebenzayo ukuvikela umthombo womsindo kusuka ku-radialing ngaphandle, okuvinjelwe umthombo womsindo; Inhloso yokuvikelwa kokuzivimba ukuvikela imishini ebucayi ukuthi iphazanyiswe ngumthombo womsindo, okuvikelwa imishini ebucayi. Isendlalelo sokuvikela ikhebula esivikelekile senziwa ikakhulukazi ngezinto ezingezona amabuzi ezifana nethusi ne-aluminium, futhi ubukhulu buncanyana kakhulu, obuncane kakhulu, obuncane kakhulu ukwedlula ukujula kwesikhumba kwemvamisa. Umphumela wesendlalelo sokuvikela abususelwa ekubonisweni nasekuhlolweni kwensimu kagesi kanye namandla kazibuthe ngomzimba wensimbi uqobo, kodwa ngenxa yesisekelo songqimba lokuvikela. Amafomu ahlukene aphansi azothinta ngqo umphumela wokuvikelwa. Izindlela ezihlabayo zensimu kagesi kanye nezendlalelo zamandla kazibuthe zihlukile. Okungavinjelwe, isisekelo esimisiwe esisodwa noma esiphekwe kabili singasetshenziswa.

Isifinyezo: Isisekelo Esiphethwe Sedwa:
1. Isisekelo esimisiwe esivikelekile sezintambo ezivikelwe siyasiza ekugwemeni ukuphazanyiswa kwamasimu kagesi aphansi. Ngamanye amagama, ingakugwema ukuphazanyiswa imvamisa nge-wavelength enkulu kakhulu kunobude bentambo l. l <λ 20
2. Isisekelo esiphelwe esisodwa se-Cable Shiepling ungqimba sengqimba singagwema umsindo wamanje wesikhathi esiphansi kungqimba lokuvikela. Lokhu kubangela okukhona kwamandla okuphazamisa amamodi-ngaphakathi futhi kunamandla okuphazamisa amadivayisi we-analog.
I-3. Isisekelo esiphekwe esisodwa sesihlangu sifiseleka ukuthi amasekethe azwela ukuphazamiseka okuphansi okuphansi (amasekethe we-analog).
4. Ukuguquguquka nokuphazamiseka kwaphakade kumanani aqhubekayo alinganiselwe akhombisa ukuphazamiseka okujwayelekile.

Isisekelo esiphekwe kabili:
1. Qinisekisa ukuthi ukuxhumana kwiKhabhinethi Yokulawula noma i-plug (Round Contact) kudlula endaweni enkulu yokushayela (ukunyakaza okuphansi). Kungcono ukukhetha insimbi ngensimbi kune-non-metal ku-non-iron.
2. Njengoba amanye amamojula we-analog asebenzisa ubuchwepheshe be-pulse (ngokwesibonelo: Iprosesa kanye ne- d Converter ehlanganiswe kumodyuli efanayo), kunconywa ukuvikela ukuxhumeka kwe-analog komunye. Kulesi simo kuphela, kufakwa esisekelweni esiphindwe kabili.
I-3. Ukuhanjiswa kokudluliselwa kwesihlangu sensimbi kuvame kakhulu kunalokho kwesihlangu se-wire esine-wire, futhi umphumela uhlukile izikhathi ezingama-5-10. Ayikwazi ukusetshenziswa njengekhebula lesiginali yedijithali.
4. Ukwehluleka okusebenzayo ngezikhathi ezithile kukhombisa ukuphazamiseka okuthe xaxa okuphezulu. Lokhu akunakuqedwa ngokuxhumeka kwezintambo.
I-5. Kuyazuzisa ukwehlisa isihlangu ngamaphuzu amaningi ngaphandle kwamaphethelo wekhebula.
6. Ungaxhumi isihlangu kwi-PIN ukugwema "umsila wengulube" phenomenon.
7. Njalo naka ukunaka ukungcola okufana nesihlangu kufanele kube ngaphansi kwe-1 10 kokungaphandle kwayo. Amathileyi ekhebula, ozimele bekhebula, ezinye izihlangu noma ezinye izintambo ezifanayo zingenza uhlelo lubekwe.
