Okulandelayo ngu Umehluko Phakathi Kwama-FM Omuntu Nawezohwebo | Chofoza lapha

Abantu abaningi ku-Google lo mbuzo, kodwa iningi lemiphumela yosesho libukeka liyinkimbinkimbi. Eqinisweni, ama-radio transmitters akhiqiza isignali yenkampani yenethiwekhi ngefrikhwensi ethile nge- i-oscillator, bese isignali ye-FM isakazwa nge- I-antenna ye-FM emkhathini. Qaphela ukuthi uma isignali ethile idinga ukulawulwa, kusetshenziswa imoduli kagesi. Uma engekho i FM module, isignali yefrikhwensi idluliselwa ngefrikhwensi echazwe ngaphambilini. 

Ngokwesakhiwo, umshini ongemuva kokusebenza komthumeli womsakazo uncike ku-oscillator, ngoba i-oscillator iyithuluzi lokukhiqiza isignali yenkampani yenethiwekhi. Ngaphezu kwe-oscillator, kukhona futhi idivayisi yokuphakela amandla yokunikeza isignali kagesi, imoduli yokwengeza ulwazi kusiphathi, i-amplifier yokwandisa amandla enkampani yenethiwekhi, kanye ne-antenna yokuguqula isignali ekhulisiwe ibe amaza omsakazo.

Kusukela esiphethweni sokudlulisa isignali yomsakazo, Akunzima ukubona ukuhamba komsebenzi okuphelele kokusakaza komsakazo:

1. Ukunikezwa kwamandla kwenza isidlulisi somsakazo somsakazo sithole isignali kagesi. Kuleli qophelo, singakwazi ukulungisa lawo mafindo emvamisa kanye nabanye okhiye ukuze sisebenzise isidlulisi
2. I-oscillator ikhiqiza i-alternating current. I-alternating current ekhiqizwa i-oscillator ibizwa ngokuthi i-carrier wave.
3. Imoduli izokwengeza ulwazi kugagasi lenkampani yenethiwekhi. Imodyuli inyusa kancane noma inciphisa imvamisa yesithwali (uma kuyi-FM), kuyilapho kusidlulisi se-AM, i-amplitude yesithwali iyahluka ngokulingana nesiginali eshintshiwe.
4. I-amplifier ye-RF izokwandisa amandla e-wave yenethiwekhi. Lapho umsebenzi we-amplifier uqina kusidlulisi, kulapho ukusakaza kuvunyelwa khona yilo msakazi wokusakaza.
5. Isekhethi yokufanisa (ishuna ye-antenna) idlulisela amandla ku-antenna ngokufanisa isidlulisi esivimbelayo ku-antenna (noma ulayini wokudlulisa we-impedance ngendlela efanele kwi-antenna). Uma lokhu kuvinjelwa kungalingani, kuzoholela esimweni esibizwa ngokuthi igagasi elimile, lapho amandla avela khona ukusuka ku-antenna kuya ku-transmitter futhi amoshwe, ngezinye izikhathi isidlulisi sokusakaza singase sishise kakhulu futhi siphuke.
6. I-antenna yokusakaza izoguqula isignali ekhulisiwe ibe amaza omsakazo. Isiteshi somsakazo esinombhoshongo wokusakaza oqinile singase sibe nokusakaza okungcono kakhulu.
7. Uma umsindo uguqulwa ube amaza anesine futhi udluliswa, inqubo yokudlulisa amasignali omsakazo iyenzeka. Ubude begagasi le-sine buyashintshwa ngokulungiswa kwefrikhwensi ukuze budluliselwe kumamukeli we-FM.
8. Umtshina osemsakazweni ube usuguqula i-sine wave wesiteshi somsakazo ube umsindo, futhi isikhulisi somsindo sinyusa ivolumu yaso.

Uma ufundile mayelana nokuhlukaniswa kwe imishini yesiteshi somsakazo kanye nezimiso zabo zokusebenza ngokulandelana kwazo ngaphambili, uzokwazi ukuthi izinhlelo ezilalelwayo ezisakazwa emsakazweni empeleni zidlula inqubo ebonakala iyinkimbinkimbi kodwa elula kakhulu.

Isignali iqala uhambo lwayo ngendlela ye-sine wave. Lapho uhambo lwayo luqala, kwakungekho lwazi olufihliwe kuyo. Uma ulwazi luthola isignali ye-electromagnetic, luyarekhodwa. Lawa maza kagesi anamandla kunamagagasi ayimishini ngoba akwazi ukudlula endaweni engenalutho ngesivinini sokukhanya. I-FM imele i-frequency modulation, okusho ukuthi ingaphinda ikhiqize umsindo emthonjeni. Yingakho iziteshi ze-FM zingadlala iziteshi zomculo ezisezingeni eliphezulu.

Kwesinye isikhathi asiwuzwa umsakazo. Lokhu ukwehluleka kokudlulisela okubangelwa igagasi elifushane. Amagagasi amafushane ahamba ngomugqa oqondile kude noqweqwe lomhlaba. Ngenxa yokuthi umhlaba uyindilinga, isignali izophazamiseka. Imvamisa, izintaba, amabhilidi amade, kanye nobude bokufakwa kwezimpondo zomsakazo we-FM kungase kube izinto ezithiya ukudluliswa kwesignali yomsakazo ngesikhathi sokusakazwa kwesignali yomsakazo.
