Fumana isicwangciso esipheleleyo sesisombululo senethiwekhi se-zoom yakho.
Zeziphi iingxaki zonxibelelwano olungenazingcingo ezisonjululwe kukuvela kwee-amplifiers zesignali?
Ngophuhliso olukhawulezileyo lweenethiwekhi zonxibelelwano eziphathwayo, okudala indlela yokuphila elula ngakumbi nangakumbi, le ndlela yokuphila elula yenza abantu baphendule ngakumbi kwiifowuni ezikrelekrele kunye neenethiwekhi, kodwa kudla ngokubakho iindawo apho inethiwekhi ingagubungeli khona. Nangona kunjalo, ngenxa yokuba amaza e-electromagnetic asasazwa kumgca othe tye, adla ngokuphazamiseka kwiindawo ezilandelayo, umzekelo: ngaphakathi kwezinye izakhiwo ezinde, amagumbi angaphantsi komhlaba, iivenkile ezinkulu, iindawo zokutyela, amagumbi asekhaya, iindawo zokuzonwabisa kunye nezinye iindawo ezininzi, unxibelelwano olungenazingcingo lusenamakhonkco athile abuthathaka angenakuhlangabezana neemfuno zabathengi, kwaye isignali yeselfowuni ibuthathaka kangangokuba ifowuni ayinakusetyenziswa ngokuqhelekileyo. Okwangoku, kukho iingxaki ezilandelayo ikakhulu.
Ngoko ke, yintoni eyenza esi siphumo?
Apha senza isigqibo sokukuchazela izizathu kunye neengcebiso zokulungisa ingxaki enokwenzeka.
1. Indawo engaboniyo:Indawo ikude kakhulu nesikhululo sesiseko, ayikho kuluhlu lwemitha yesikhululo sesiseko nto leyo ebangela imeko yendawo engaboniyo isignali.
2. Indawo ebuthathaka: Isizathu esiphambili kukuba isignali iphantsi kunendlela ifowuni ephathwayo efumana ngayo emva kokulahleka, nto leyo ebangela ukuba iifowuni eziphathwayo zingabi mnandi.
3. Indawo yengxabano: ikakhulu kwindawo yesakhiwo esiphakamileyo, imiqondiso engenazingcingo ivela kwiiseli ezininzi, kwaye uninzi lwazo ziimpawu zokubonakalisa ezingazinzanga ezivela emhlabeni nakwiindonga, nto leyo ebangela ukutshintsha rhoqo (oko kukuthi isiphumo se-ping-pong), nto leyo echaphazela kakhulu unxibelelwano oluqhelekileyo lweefowuni eziphathwayo.
4. Indawo exakekileyo: Ngokuyintloko yindawo enezithuthi ezininzi. Inani labasebenzisi kule ndawo lidlula umthwalo wesikhululo seenqwelo-moya ngexesha elinye, kwaye abasebenzisi abanakufikelela kwinethiwekhi yeselula ukuze bafumane unxibelelwano oluqhelekileyo.
Nangona kunjalo, i-amplifier yesignali yefowuni ephathwayo yimveliso eyenzelwe ngokukodwa ukusombulula ezi ndawo zibuthathaka zesignali zefowuni eziphathwayo. Ii-amplifier zesignali yefowuni ephathwayo zineempawu zobukhulu obuncinci kunye nokufakelwa okuguquguqukayo, kwaye zinokubonelela ngokugubungela okunzulu kwesignali zangaphakathi. Kubonakalise ukuba zinokubonelela ngezibonakaliso ezizinzileyo nezithembekileyo kubasebenzisi bonxibelelwano lwefowuni ephathwayo lwangaphakathi, ukuze abasebenzisi nabo bonwabele iinkonzo zonxibelelwano lomntu ezikumgangatho ophezulu ngaphakathi.
