Ngokuthuthuka kobuchwepheshe, ukuncika kwethu kumasiginali angenantambo kuyakhula.Kodwa-ke, ezindaweni ezithile ezithile, njengezindlu ezingaphansi, amasignali angenantambo avame ukuphazamiseka kakhulu, okuthinta ukusetshenziswa okuvamile.Ngakho-ke, ubuchwepheshe bokukhulisa isignali engaphansi buye bavela.Okulandelayo, sizocubungula isimiso sokusebenza, ukusetshenziswa, kanye nokubaluleka kokukhulisa isignali engaphansi ekuxhumaneni kwesimanjemanje.
1. Umgomo wokusebenza wokukhulisa isignali engaphansi
1.1 Ukwakhiwa kwezisetshenziswa
I-amplifier yesignali engaphansi ngokuyinhloko iqukethe izingxenye ezintathu: i-antenna, i-amplifier, kanye nomsabalalisi wesignali.Lezi zingxenye ezintathu zisebenza ndawonye ukuze kuzuzwe ukudluliswa okuphumelelayo kwamasignali angenawaya ezindaweni ezingaphansi komhlaba.
1.2 Inqubo yokusebenza
Isikhulisi sesignali siqale samukele amasiginali angenantambo abuthaka kusuka othini, bese sithuthukisa amandla esiginali nge-amplifier, bese sisabalalisa isignali eqinisiwe ezindaweni ezihlukene zesitezi esingaphansi ngomsabalalisi wesignali ukuze kuzuzwe ukuxhumana okungenantambo okuzinzile.
2. Ukusetshenziswa kokukhulisa isignali engaphansi
2.1 Isicelo ezakhiweni zokuhlala nezohwebo
Ezindaweni eziningi zokuhlala nezokuhwebelana, amagumbi angaphansi asetshenziswa njengezindawo zokupaka izimoto, izindawo zokugcina izinto, noma izindawo zamahhovisi.Kulezi zindawo, ukushelela kwamasignali angenantambo kubaluleke kakhulu.Ama-amplifiers esignali adlala indima ebalulekile kulezi zimo zohlelo lokusebenza.
2.2 Isicelo Ezikhungweni Zomphakathi
Ezindaweni zomphakathi ezifana neziteshi zesitimela ezingaphansi komhlaba kanye nezindawo zezitolo ezingaphansi komhlaba, kunesidingo esikhulu samasignali angenantambo ngenxa yobuningi babantu.I-amplifier yesiginali engaphansi ingathuthukisa ngempumelelo ukumbozwa kwesiginali kanye nekhwalithi kulezi zindawo.
isiphetho
Sekukonke, ubuchwepheshe bokukhulisa isignali engaphansi iyithuluzi elibalulekile lokuxazulula izinkinga zokuxhumana ezindaweni ezingaphansi komhlaba.Ngokuqonda kanye nokuba ingcweti umgomo wokusebenza kanye nokusetshenziswa kokukhulisa isignali engaphansi, singaxazulula kangcono izinkinga zokuxhumana ezindaweni ezingaphansi komhlaba futhi sithuthukise ikhwalithi nokusebenza kahle kokuxhumana okungenantambo.Ngokuzayo, ngokuthuthuka kobuchwepheshe, sinesizathu sokukholelwa ukuthi ubuchwepheshe bokukhulisa isignali engaphansi buzoba nokuqanjwa okusha kanye nezinhlelo zokusebenza, okulethe ukunethezeka okwengeziwe ezimpilweni zethu nasemsebenzini.
