Yintoni i-amplifier yomsindo weTV?

Ekubeni kwezinto eziphazamisa ukuhanjiswa kwegama, kunye nokude kakhulu kumthombo wokusasazwa, umgangatho wokusasazwa uya kuba phantsi. Kwaye kunye nezixhobo zanamhlanje (i-TV enhle, i- receiver, i-antenna) ayikwazi ukuqinisekisa umfanekiso ocacileyo kwiskrini seTV. Kwiimeko ezinjalo, kungcono ukuthenga umtsalaneli womboniso weTV oza kunika umgangatho ozwakalayo kunye nokucaciswa komfanekiso, kungakhathaliseki ukuba indawo yendawo kunye neemeko zemozulu.

Kwinkqubo yokukhetha i-amplifier, kufuneka uqikelele amandla esi sixhobo kunye nobukhulu begumbi. Iifayile ezifanayo ze-antenna kufuneka zisetyenziswe ukuba umqondiso uphendulelwe kwiimvume ezininzi. Zisetyenziselwa ukukhulisa amaza aphezulu. Umgangatho weenkqubo ezithile ezincedisayo zixhomekeke ngokuthe ngqo kumhlobo we-antenna ezisetyenziswayo kunye nesixhobo esifumana isignali.

Ezinye iimodeli zenzelwe ukusebenza kwiimeko ezihambelana nesimo sezulu. Ziyakhuselwa ngokuphazamiseka kwe-electromagnetic, kwaye umzimba wabo uhlanganiswe ngengubo ekhuselekileyo yokukhusela. Ngokuqhelekileyo kukho amaxesha apho kufuneka uhlukanise ikhebula kwiiTV ezininzi. Umtsalaneli womboniso weTV uvumela ukuba wenze oku ngelahleko encinci.

Isixhobo esikhethekileyo esidibanisa ne-antenna (okanye singeniswe kuyo) kwaye siphucula kakhulu umgangatho wokusasazwa ngumvelisi we-TV. I-Amplifier yeSignal yeTV Kukho utshintsho oluhlukileyo. Njengomthetho, kuyimfuneko ukuyikhetha phantsi kokhokelo lwengcali kule ndawo. Ukusebenza kwezi nkqubo kuxhomekeke kwiimeko zokumkela kunye nekhnoloji edibene kuyo.

Ezinye izibonakaliso zezibonakaliso zenzelwe ukukhulisa amaza omabonwakude owamkela kunye kunye nomboniso wekhamera kwinethiwekhi yokusabalalisa indlu. Zingasetyenziselwa kwiindawo zokuhlala ezihlukeneyo kunye neekotishi xa zisetyenziswa kwinani elikhulu lamacebo omabonwakude.

Amaplifiers angasetyenziselwa ukutshintsha kweqondo lokushisa ukusuka -40 ^o C ukuya ku-50 ^o . C. Ubuncwane obunxulumene nomoya bunokufikelela kuma-98% ngomqondiso kwi-thermometer ye-25 ^o C.

I-Antenna amplifier yesignali yeTV yokusetyenziswa komntu ngamnye yenzelwe ukwandisa umgangatho xa ufumana umbala kunye nemifanekiso emnyama nemhlophe. Yenzelwe umsebenzi odibeneyo kunye nabamkeli bamabonwakude kuzo zonke iindidi kunye neeklasi. Ngokuxhomekeka kwiimvama, i-antenna amplifiers zenzelwe imitha, i-decimeter kunye nemitha eneendidi ze-decimeter. Amaplifiers angafakwa kwi-mast eduze kwe-antenna okanye efakwe kufuphi nommkeli womabonakude.

Ukuba, ngenxa yezizathu ezahlukahlukeneyo, awukwazi ukudibanisa kumabonwakude, kunye ne-antenna yasekhaya, umgangatho wokwamkelwa kwee-TV ezishicilelweyo kushiya into enokuyifisa, ngoko umtsalaneli womboniso weTV unokusombulula le ngxaki. Ayikunceda kuphela ngesignali engalunganga kunye nokuphazamiseka, kodwa nangona amaza omabonwakude ehlala ephela ngokupheleleyo, ngelixa ehamba kuphela imfucumfucu ekhanda kwisikrini. Ukuqhagamshela le nkqubo elula kunye ne-antenna ikuvumela ukuba wenze umgangatho wesithombe kwisikrini esizinzile. Ngaliphi na ixesha lemihla kwaye kungakhathaliseki ukuba iimeko zemozulu, i-amplifier ye-antenna iqinisekisa umfanekiso ocacileyo kunye nesandi esihle.
