Kwamanye amazwe, ukuqubuka kwenkonzo yesonto ye-covid-19 enomkhawulo wokuxhumana ubuso nobuso, futhi amasonto amaningi kudingeke ukuthi avalwe isikhashana. Ngenhlanhla, isonto elithile elingena ngaphakathi likwazile ngempumelelo izinsiza zokusakaza zesonto le-FM - ukuthumela amasignali okusakaza emsakazweni wezimoto zezethameli ngokusebenzisa Umsakazi womsakazo we-FM, uthi lwe-FM, nokunye okukhethekile imishini yesiteshi somsakazo. Ngokungafani nenkonzo yesonto lokuxhumana, ukusakazwa kwesonto nge-drive-in kudinga kuphela isidluliseli sokusakaza sekhwalithi ephezulu, i-antenna yokusakaza, indawo encane yokusakaza, ugesi, nokunye okuyisisekelo. imishini yokusakaza emsakazweni esontweni. Njengomongo wemishini yesiteshi somsakazo wesonto, isidlulisi se-FM sinquma ikhwalithi nendlela yokusakaza. Ku-opharetha wesonto, indlela yokukhetha ikhwalithi ephezulu Umsakazi womsakazo we-FM?

Imibuzo Evame Ukubuzwa

Isiphetho

Umsakazi womsakazo we-FM iyimishini ewumgogodla ye-drive-in church, ngakho-ke umbuzo uwukuthi, yini i-FM Transmitter?

Ngokwencazelo yeWikipedia, umsakazi we-FM kuyingxenye ebalulekile yakho konke ukuxhumana ngomsakazo. Ikhiqiza i-radio frequency alternating current, esetshenziswa ku- I-antenna ye-FM. Lapho ijatshuliswa yilokhu kushintshana kwamanje, i I-antenna yomsakazo we-FM ikhipha amaza omsakazo.

Ngamafuphi, isidlulisi somsakazo we-FM iyithuluzi le-elekthronikhi eliguqula isignali yomsindo eyamukelwe ibe yisignali ye-RF bese iyidlulisela ngothi lwe-FM.

Kungani iyona Umsakazi womsakazo we-FM esikhundleni se-AM radio transmitter esontweni lokungena? Ilandisa ngendlela asebenza ngayo.

I-FM isho ukuguqulwa kwemvamisa, kuyilapho i-AM isho ukushintshashintsha kwe-amplitude. Bahlela amasignali ngezindlela ezahlukene. I-FM idlulisa amasiginali ngoshintsho lwemvamisa, kuyilapho i-AM idlulisela amasignali ngoshintsho lwe-amplitude, okuwenza abe nezici ezihlukile:

• Njengoba i-FM inomkhawulokudonsa ophezulu, umsakazo we-FM uzwakala kangcono kunomsakazo we-AM;

• Uma kuqhathaniswa ne-AM, i-FM ayithinteki kangako ekuphazamisekeni koshintsho lwe-amplitude, ngakho isignali ye-FM izinzile;

• Isakaza i-AM ngamagagasi aphakathi nendawo namade aphansi, kuyilapho i-FM isakaza ngamaza amakhulu amagagasi amagagasi namaza amafushane, ukuze amasiginali e-AM aye kude, kodwa amasignali e-FM adlulisa ibanga elifushane.

Ngokuvamile, umsakazi we-FM ungcono esontweni elingena ngaphakathi. Ngoba uhla oluncane lokufakwa kwesiginali lungahlangana nesonto lokushayela. Kubalulekile ukuthi amakholwa ezwe kahle izwi lomfundisi njengenjwayelo. Ngakho-ke, abefundisi abaningi babheka ukubaluleka okukhulu kwekhwalithi yomsindo, yingakho bekhetha umsakazi we-FM ku-FMUSER. Sigxila ekusebenzeni kokudluliswa komsindo kanye nokusebenza kwezindleko zabasakazi bomsakazo we-FM. Uma udinga buy Umsakazi womsakazo we-FM kusuka ku-FMUSER, sicela ukhululeke uku Xhumana nathi.

Akunzima ukusebenzisa umsakazi we-FM esontweni. Ngokusetha okulula, umpristi angaqala ukusho imibhalo kumakholwa. Nawu umhlahlandlela omfushane wokusetha wesonto lokushayela ngaphakathi:

• Okokuqala, xhuma i- I-antenna yomsakazo we-FM ne Umsakazi womsakazo we-FM ngezintambo. Lesi sinyathelo sibalulekile. Noma i Umsakazi womsakazo we-FM kulula ukudiliza futhi shayela-ke esontweni ayikwazi ukusebenza.

• Bese uxhuma i- Umsakazi womsakazo we-FM ngokunikezwa kwamandla, yivule futhi ulungise imvamisa. Akufanele kube khona ukuphazamiseka kwesignali kule frikhwensi ukuze umsindo udluliselwe ngokucacile.

• Ekugcineni, xhuma imakrofoni esetshenziswa umpristi kujekhi yomsindo we Umsakazi womsakazo we-FM.

Ngalezi zilungiselelo eziyisisekelo, i- Umsakazi womsakazo we-FM angadlulisela izwi lompristi.

Note: uma unezinye izidingo zomsindo, ungakwazi futhi ukwengeza i-mixer nephrosesa yomsindo ukuze ulungise umsindo odlulisiwe.

Ebandleni lokungena, umsakazi we-FM idlala indima yokuguqula isignali yomsindo ibe isignali yefrikhwensi yomsakazo futhi iyidlulise ngothi lwe-FM. Ngakho-ke, lezi zici kufanele zicatshangelwe lapho kukhethwa Umsakazi womsakazo we-FM ngezinkonzo zesonto zokushayela:

• Amandla we Umsakazi womsakazo we-FM - Amasonto amaningi angena ngemoto awamakhulu, ngakho-ke amandla omsakazo we-FM akufanele abe phezulu kakhulu. Ngokusho kokuhlangenwe nakho okungokoqobo konjiniyela bethu, a I-15W FM Transmitter ilungele kakhulu ukungena esontweni. Ngoba a I-15W FM Transmitter ingasakaza ibanga le-radius engaba ngu-3km ngokufanelekile.

• Umsindo kufanele ube mncane - I-SNR ye- Umsakazi womsakazo we-FM akufanele kube phansi kakhulu, noma amakholwa azozwa umsindo omkhulu lapho ezwa amaBhayibheli. Ngokuvamile, i-SNR yayo akufanele ibe ngaphansi kuka-40dB.

• I-stereo nayo iyadingeka - isonto lokungena ngemoto kwesinye isikhathi lidlala umculo othile. Uma usebenzisa Iziteshi zomsakazo we-FM ngokuhlukaniswa kwe-stereo ephakeme kuno-40dB, amakholwa angakwazi ukuzwa umculo onothileyo.

Iziteshi zomsakazo we-FM ukuhlangabezana nezimo ezinjalo kungenza umoya webandla uqine, futhi kulula ukuhlanganisa imizwa yamakholwa ukuze bathole ukuthula kwangaphakathi eBhayibhelini. U-FMUSER wethule i- I-15W FM stereo PLL transmitter, I-FU-15A FM stereo transmitter, eyakhelwe ngokukhethekile esontweni lokushayela, esihlangabezana ngokugcwele nezidingo ezingenhla futhi esithole ukunconywa kumakhasimende amaningi.
