Okuqukethwe

 

Ulwazi Oluyisisekelo Okufanele Ulwazi

 

An i-analog TV transmitter is a Imishini yokusakaza ye-TV esetshenziselwa ukusakazwa kwe-TV emoyeni. Ikhanyisa amaza omsakazo athwala amasignali evidiyo namasignali alalelwayo ekumbozweni, futhi amele izithombe ezihambayo nomsindo ovumelanisiwe. 

 

Amandla e-analog TV transmitter ayahluka ukusuka ku-50w ukuya ku-10kw. Isakaza amasiginali we-TV ebangeni lefrikhwensi ye-VHF ne-UHF. Futhi isetshenziswa kabanzi eziteshini zokusakaza ze-TV ezahlukahlukene.

 

Isebenza kanjani i-Analog TV Transmitter?

 

I-Analog TV transmitter ingenye yezingcezu ezibaluleke kakhulu zemishini yokusakaza ye-TV. Isetshenziselwa ukusakaza amasiginali we-TV kubamukeli be-TV ekukhaveni, futhi abantu bangawamukela nge-TV eyamukela i-antenna.

            

Ngokuvamile, iqeda umsebenzi wokusakaza amasiginali we-TV ngezinyathelo ezi-3:

 

1. Ithola amasignali e-TV eziteshini ze-TV ngesixhumanisi se-studio transmitter.

2. Izocubungula amasignali e-TV futhi iwaguqulele amandla kagesi. Isibonelo, isidluliseli se-TV ye-analogi siguqule amasiginali we-TV kumagagasi esiphathi somsakazo ebangeni elithile lefrikhwensi.

3. Imali ye-elekthronikhi izodluliselwa ku-antenna esakaza i-TV futhi ikhiqize amaza omsakazo ngendlela yamasignali e-analog. I-antenna ye-TV yayizobasakaza.

 

 

Amathiphu angu-5 Wokukhetha I-TV ye-Analog Engcono Kakhulu

 

Umsakazi we-TV we-analogi wekhwalithi engcono kakhulu ubalulekile ezinkampanini ezisakaza i-TV ngoba ukusakazwa kwe-TV kuyinkonzo yomphakathi ebalulekile eqinile ngekhwalithi yokusakaza kwe-TV. Ngakho-ke ungasikhetha kanjani isidluliseli se-analog TV sesiteshi sakho somsakazo we-TV?

Ukusebenza Okuhle

Ukusebenza kubalulekile. I-TV ye-analog enamandla amakhulu ingamboza ikhava enkulu. Umsebenzi omuhle kakhulu wevidiyo nomsindo unganikeza ababukeli umuzwa ongcono kakhulu wokulalela nokubuka. Umkhawulokudonsa omkhudlwana enawo, kulapho iziteshi eziningi ezingawudlulisa. Kusho ukuthi ungakwazi ukuheha ababukeli abaningi futhi ulethe izinzuzo ezengeziwe kubasakazi be-TV.

Amapharamitha Okhiye

Nawa amapharamitha angu-3 abalulekile wesidlulisi se-TV ye-analog okufanele uwanake ngaphambi kokufaka ama-oda:

 

  • Ukudlulisa Amandla - Amandla omsakazo we-TV anquma ukumbozwa kanye namandla okungena kwezimpawu ze-TV. Uma unemibuzo mayelana nokukhetha izinga lamandla, ungangabazi ukuthintana nochwepheshe wethu we-RF.

 

  • Komkhawulokudonsa - I-bandwidth isho ububanzi befrikhwensi. Umkhawulokudonsa obanzi ungaqukatha ulwazi olwengeziwe, okusho ukuthi isidlulisi se-TV ye-analogi singasakaza iziteshi eziningi ze-TV

 

  • Ukucindezelwa kwe-Clutter kanye nokucindezelwa kwe-Harmonic - Ukucindezela imfuhlumfuhlu nokucindezelwa kwe-harmonic kunganciphisa izici ezingazinzile lapho isidlulisi se-TV ye-analogi sisakaza amasignali we-TV futhi sivikele umshini ekubhidlikeni. Ngakho-ke ukucindezelwa okuphansi kwe-clutter nokucindezelwa kwe-harmonic kungcono.

Ukuzinza Okunokwethenjelwa

Akukhona nje ukusebenza okubalulekile, kodwa futhi ukuzinza kuyakwenza. Isidluliseli se-TV se-analogi esithembekile singasakaza ngokuqhubekayo isikhathi eside futhi sigweme ukuphuka. Ngenxa yokuthi cishe akunakwenzeka ukuba ukwehluleka, kunganciphisa kakhulu izindleko zokusebenzisa abasakazi be-TV futhi kunikeze umuzwa ongcono kakhulu wokubuka wababukeli. 

Ukuphepha Nokuvikelwa

Umsebenzi wokuphepha nokuvikela uyadingeka ku-TV ye-analog transmitter. Ukusebenza isikhathi eside kuvame ukuholela ezingeni eliphezulu lomonakalo emshinini. Ngaphandle komsebenzi wokuphepha nokuvikela, isidlulisi se-TV ye-analogi cishe siyaphuka bese siholela ekulimaleni kwezinto ezisetshenziswayo ezizungezile.

Ubungane Bomsebenzisi

Umklamo omuhle womkhiqizo kufanele ucabangele izidingo zabasebenzisi futhi ukwazi ukuthuthukisa ukusebenza kahle kwabo. Isibonelo, isikrini esicacile kanye nesixhumi esibonakalayo sokusebenza esiklanywe ngokunengqondo kungasiza kakhulu opharetha ukuthi bathole i-hang of the analog TV transmitter ngokushesha. Ngokusobala, kuyasiza ukuthuthukisa ukusebenza kahle kwabo.

Umkhiqizo othembekile

Okokugcina, kufanele ukhethe uhlobo olungcono kakhulu olethembayo. Ibhrendi ethembekile ethembekile ingakunikeza isidlulisi se-TV se-analogi esingcono kakhulu futhi ithuthukise ukusebenza kahle komnotho wenkampani yokusakaza ye-TV.

 

Uma udinga usizo ngesidlulisi se-TV se-analogi noma esinye isisetshenziswa sokusakaza se-TV, singakunikeza ukwesekwa okufika ngesikhathi kanye nezeluleko eziwusizo kakhulu. Akungabazeki ukuthi uhlobo oluthembekile oluthembekile lunganciphisa izindleko nengcindezi yazo zonke izici zakho nganoma yisiphi isikhathi.
