Isevisi ye-Drive-in ingelinye lamabhizinisi omsakazo aziwa kakhulu. Inganikeza ukuzijabulisa okukhululekile nokujabulisayo koquqaba. Ingenye yezindlela zokuzijabulisa ezaziwa kakhulu ngaphansi kwalolu bhubhane.

Abantu abaningi bafuna ukushayela ezinsizeni zokusakaza. Uma ufuna ukwenza ibhizinisi lakho lenkonzo yokushayela ligqame emqhudelwaneni oshubile, udinga imishini yesiteshi somsakazo ehamba phambili. Akungabazeki ukuthi isidluliseli samandla aphansi we-FM sekhwalithi ephezulu singakulethela ibhizinisi elengeziwe. Kepha uyazi ukuthi ungasikhetha kanjani isidluliseli samandla aphansi we-FM esingcono kakhulu sokushayela ngaphakathi?

Ngesipiliyoni seminyaka eminingi yokusakaza umsakazo, i-FMUSER izokwethula ukuthi kungani kufanele usebenzise isidluliseli somsakazo we-FM kanye nengxenye ebaluleke kakhulu: ungasikhetha kanjani isidluliseli se-FM esinamandla aphansi ukuze ungene ngaphakathi. Masiqhubeke sihlola!

Kungani i-Low Power FM Transmitter ye-Drive-in Matters?

Isidluliseli samandla aphansi we-FM siyisisetshenziswa sesiteshi somsakazo esiphakathi nendawo sokushayela ezinkonzweni, futhi sithatha izingxenye zokudlulisa umsindo nokudlulisa amasignali omsindo. Kepha kungani kubalulekile futhi awukwazi ukuthola ukuthi i-AM transmitter isetshenziswa ezinsizeni zokushayela?

I-FM idlulisa amasignali alalelwayo ngokungashintshi - I-FM imele ukuguqulwa kwefrikhwensi, futhi iyindlela yokudlulisa amasignali omsindo. Uma kuqhathaniswa nesidluliseli se-AM sendabuko, isidlulisi esinamandla aphansi we-FM siza nokudluliswa komsindo okucacile nokuzinzile. Kusho ukuthi unganikeza umuzwa ongcono wokulalela kumakholwa.

Ama-FM anezindleko zebhajethi - Ngenxa yokuthuthukiswa kobuchwepheshe, manje umsakazi we-FM osezingeni eliphezulu ubiza kancane. Isengasetshenziswa ezinhlelweni zokusakaza zomsakazo eziningi, okuhlanganisa izinsiza zokungena, umsakazo womphakathi, umsakazo wesikole, njll.

Ngamafuphi, isidluliseli samandla aphansi we-FM sinezici zekhwalithi yomsindo esezingeni eliphezulu nezintengo zebhajethi ukuze kube ukukhetha kokuqala kulabo abafuna ukuqala ibhizinisi lokushayela.

6 Amathiphu Okuthenga Isidluliseli Samandla Aphansi FM

Amapharamitha wobuchwepheshe bokufunda awusizo kithi lapho sikhetha isidluliseli samandla aphansi we-FM esingcono kakhulu. Kodwa-ke, umsakazi ngamunye we-FM unemingcele eminingi, futhi yimuphi okufanele sigxile kuwo? Ngenhlanhla, i-FMUSER ifinyeza amathiphu angu-6 ayinhloko okukhetha isidlulisi se-FM esinamandla aphansi sokungena.

Imvamisa Egcwele Njalo

Umsakazi womsakazo we-FM onefrikhwensi yobubanzi obugcwele ungahlinzeka ngamashaneli amaningi ongakhetha kukho futhi ukusize ugweme ukuphazamiseka kwamasignali e-FM. Kungani ungakhethi abasakazi be-FM abanobubanzi obugcwele bemvamisa? Uma usuqaphela ukuthi kukhona ukuphazamiseka kwesignali nxazonke, ungalungisa isidlulisi se-FM futhi uthole imvamisa engasetshenzisiwe ukuze udlulise amasignali e-FM acacile ngaphandle.

Ikhwalithi ephezulu yomsindo

Ikhwalithi yomsindo ibalulekile ngempela ngoba inquma umuzwa wokulalela. Ikhwalithi yomsindo engcono ingakusiza uhehe abalaleli abaningi futhi ukhulise ibhizinisi lakho. Ngakho-ke udinga ukufunda incazelo yokuhlukaniswa kwesitiriyo somsindo namanye amapharamitha omsindo, njll. Ngokuvamile, ukuhlukaniswa kwesitiriyo somsindo esingu-40 dB kanye ne-SNR engu-65 dB kwamukelekile.

Amandla Okudlulisa Okuchichimayo

Umsakazi womsakazo we-FM onamandla amaningi okudlulisa ungaqinisekisa ukuthi ungahlinzeka ngezinsizakalo zokusakaza kubo bonke abalaleli. I-Effective Radiated Power (ERP) inquma ukuthi zingakanani izindawo ongazidlulisela. Okufanele ukuqonde ukuthi, i-ERP ayilingani namandla okudlulisa, futhi kuncike emandleni okudlulisela kanye nokusebenza kwe-antenna yokusakaza ye-FM. Kuyalulekwa ukuthi ukhethe isidlulisi samandla aphansi we-FM esinamandla okudlulisa angaphezu kwalokho obulindele, bese ungaqinisekisa ukuthi une-ERP eyanele.

Intengo Yesabelomali

Isihambisi samandla aphansi we-FM esinenani lesabelomali siyisihluthulelo sethu sokugcina. Kodwa akusho ukuthi kufanele uyeke izici ezithile ezibalulekile zomsakazo we-FM. Okubaluleke kakhulu, kufanele ukhethe isidluliseli se-FM esinamandla aphansi esilingana nesabelomali sebhizinisi lakho lokungena ngaphandle kokubeka engcupheni ikhwalithi yaso, ubuqotho, nokusebenza kwayo.

Ukusebenza okulula

Ukusebenza okulula kunganciphisa izinkinga eziningi ezicasulayo kuwe. Isibonelo, izinkinobho eziklanywe ngendlela ephusile zingakusiza ukuthi ulungise kalula isidluliseli somsakazo we-FM futhi ugweme ukusebenzisa kabi ngangokunokwenzeka. Futhi uma kukhona isikrini se-LCD esicacile esifakwe kuso, ungafunda mayelana nesimo somsakazo we-FM ngokuqondile futhi wazi izinkinga ngesikhathi.

Qedela Imisebenzi Yokuvikela Okuphephile

Umsebenzi wokuvikela ukuphepha ungavala umshini ngesikhathi uma kwenzeka umshini wehluleka ukugwema ukulahlekelwa okwengeziwe. Umsebenzi wokuvikela ukuphepha yilokho ongeke ukushaye indiva lapho ukhetha isidluliseli somsakazo we-FM esingcono kakhulu. Kufanele ikwazi ukuqala indlela yokuvikela ngesikhathi uma kwenzeka indawo enzima, njengokushisa ngokweqile, ukupholisa ngokweqile, amanzi, njll.

Ngamafuphi, sidinga ukugxila kumaphuzu ayi-6: ububanzi obugcwele befrikhwensi, ikhwalithi yomsindo ephezulu, amandla amaningi okudlulisa, ukusebenza okulula, izintengo zebhajethi kanye nemisebenzi ephelele yokuvikela ephephile. Sithemba ukuthi lawa macebiso angaba usizo kuwe. Njengomphakeli ohamba phambili wokusakazwa komsakazo we-FM, i-FMUSER ingakunikeza izisakazi zomsakazo we-FM amandla okudlulisela ehluka ukusuka ku-0.5 watt kuya ku-10000 watt kanye namaphakheji aphelele wemishini yesiteshi somsakazo. Uma unentshisekelo kubo, sicela ukhululeke ukuyihlola!

imibuzo ejwayelekile ukubuzwa

1. Q: Kuzosakazwa Kungakanani I-50 Watt FM Transmitter?

A: I-transmitter engu-50 watt FM ingasakaza cishe amakhilomitha ayi-10.

Yebo, sithe isidlulisi se-watt FM esingu-50 singasakaza cishe amakhilomitha ayi-10. Kodwa akulungile, ngoba ukufakwa okuthintekayo izinto eziningi, okuhlanganisa amandla okudlulisa, ukuphakama kokufakwa kwe-antenna yomsakazo we-FM, izithiyo ezizungezile, ukusebenza kwe-antenna, njll.

2. Umbuzo: Yiziphi Izisetshenziswa Okufanele Ngibe Nazo Esiteshini Somsakazo Amandla Aphansi FM?

A: Okungenani kufanele ube nesidluliseli samandla aphansi we-FM, amaphakheji we-antenna yokusakaza ye-FM, futhi ungangeza imishini yesiteshi somsakazo eseceleni ngokuya ngezidingo zakho.

3. Umbuzo: Ingabe Kusemthethweni Ukuqala Isiteshi Somsakazo Esinamandla Aphansi?

IMP: Yebo, uma usifakile isicelo selayisensi.

Ngokuvamile, ukuqalisa isiteshi somsakazo esinamandla aphansi we-FM kusemthethweni emhlabeni wonke, kodwa iziteshi zomsakazo eziningi ze-FM zilawulwa uhulumeni. Ngakho-ke udinga ukufaka isicelo selayisensi kuqala, futhi ufunde ngemithetho ehlobene ukuze ugweme ukujeziswa.

4. Q: Iyini i-Effective Radiated Power (ERP)?

A: Amandla emisebe asebenzayo (ERP) amele amandla okudlulisa amasistimu e-RF.

I-ERP iyincazelo emisiwe yamandla omsakazo oqondisayo (RF). Uma ufuna ukubala, udinga ukwazi amandla okudlulisa omsakazo we-FM, bese ususa ukulahlekelwa kuma-duplexers nanoma yikuphi ukulahleka komugqa wokuphakelayo okungakalwa, futhi ekugcineni udinga ukwengeza inzuzo ye-antenna.

Isiphetho

Ukufunda ukuthi kungani kufanele usebenzise isidluliseli samandla aphansi we-FM ebhizinisini lokushayela kanye namathiphu ayi-6 ayinhloko okuthenga omsakazo onamandla aphansi we-FM wokungena kungakusiza ukuthi uqale ibhizinisi lakho lokushayela kangcono. Sinesipiliyoni samashumi eminyaka ekusakazeni emsakazweni, sisize izinkulungwane zamakhasimende ukuthi azakhele isiteshi somsakazo se-FM esinamandla aphansi, futhi sabanikeza iziphakamiso zobungcweti kanye nesabelomali semishini yomsakazo enamandla aphansi, njengesidlulisi samandla aphansi we-FM esithengiswayo, i-antenna ye-FM. amaphakheji, njll. Sikholwa ukuthi lolu lwazi lungakulethela amakhasimende amaningi kanye nenzuzo. Uma ufuna okwengeziwe ngebhizinisi lokungena, sicela ukhululeke ukusithinta!
