An analog TV transmitter yog ib tug Cov khoom siv tshaj tawm hauv TV siv rau kev tshaj tawm hauv TV tshaj tawm. Nws radiates xov tooj cua nthwv dej uas nqa cov teeb liab video thiab audio signals rau qhov kev pab cuam, thiab lawv sawv cev rau cov duab txav thiab lub suab synchronized. 

Lub zog ntawm analog TV transmitter txawv ntawm 50w mus rau 10kw. Nws tshaj tawm TV teeb liab nyob rau hauv ntau zaus ntawm VHF thiab UHF. Thiab nws yog dav siv nyob rau hauv ntau yam TV transmitter chaw nres tsheb.

Analog TV transmitter yog ib qho tseem ceeb tshaj plaws ntawm cov khoom siv tshaj tawm hauv TV. Nws yog siv los tshaj tawm cov xov tooj cua hauv TV rau cov neeg txais TV hauv qhov kev pab cuam, thiab tib neeg tuaj yeem tau txais lawv los ntawm TV txais xov tooj cua.

Feem ntau, nws ua tiav txoj haujlwm ntawm kev tshaj tawm TV teeb liab hauv 3 kauj ruam:

1. Nws tau txais cov teeb liab TV los ntawm TV chaw nres tsheb los ntawm studio transmitter txuas.

2. Nws yuav ua cov teeb liab TV thiab hloov mus rau hauv hluav taws xob tam sim no. Piv txwv li, analog TV transmitter modulated lub TV teeb liab mus rau lub xov tooj cua cab kuj yoj nyob rau hauv tej zaus.

3. Cov txiaj ntsig hluav taws xob yuav raug xa mus rau TV xa xov tooj cua thiab tsim cov xov tooj cua tsis muaj zog hauv daim ntawv ntawm cov cim analog. TV kav hlau txais xov yuav tshaj tawm lawv.

Qhov zoo tshaj plaws-zoo analog TV transmitter yog qhov tseem ceeb rau TV tshaj tawm cov tuam txhab vim hais tias TV tshaj tawm yog ib qho tseem ceeb rau pej xeem kev pab cuam uas yog nruj me ntsis raws li zoo ntawm TV tshaj tawm. Yog li yuav ua li cas xaiv qhov zoo tshaj plaws analog TV transmitter rau koj lub TV transmitter chaw nres tsheb?

Kev ua tau zoo yog qhov tseem ceeb. Ib qho analog TV transmitter nrog lub zog siab tuaj yeem npog qhov loj. Kev ua yeeb yaj kiab thiab suab zoo tuaj yeem muab cov neeg saib nrog kev mloog zoo tshaj plaws thiab saib kev paub. Qhov loj bandwidth nws muaj, ntau cov channel nws tuaj yeem xa mus. Nws txhais tau tias koj tuaj yeem nyiam cov neeg saib ntau dua thiab nqa cov txiaj ntsig ntau dua rau cov tshaj tawm TV.

Nov yog 3 qhov tseem ceeb ntawm qhov analog TV transmitter uas koj yuav tsum tau them sai sai rau ua ntej koj tso xaj:

• Hloov Ua Zog - Lub hwj chim ntawm TV transmitter txiav txim siab qhov kev pab them nqi thiab lub peev xwm ntawm kev nkag mus ntawm cov teeb liab TV. Yog tias koj muaj lus nug txog kev xaiv lub hwj chim theem, tsis txhob yig tiv tauj nrog peb tus kws tshaj lij RF.

• bandwidth - Bandwidth txhais tau hais tias qhov dav ntawm qhov zaus. Lub dav bandwidth tuaj yeem muaj cov ntaub ntawv ntau ntxiv, uas txhais tau hais tias analog TV transmitter tuaj yeem tshaj tawm TV ntau dua

• Clutter Suppression thiab Harmonic Suppression - Kev cuam tshuam kev sib tsoo thiab kev sib haum xeeb tuaj yeem txo qhov tsis ruaj khov thaum lub analog TV transmitter tshaj tawm TV teeb liab thiab tiv thaiv lub tshuab los ntawm kev tawg. Yog li qhov qis qis qis qis thiab kev sib haum xeeb kev sib haum xeeb yog qhov zoo dua.

Tsis tsuas yog kev ua haujlwm tseem ceeb, tab sis kuj muaj kev ruaj ntseg. Ib qho kev txhim khu kev qha analog TV transmitter tuaj yeem tshaj tawm tsis tu ncua ntev ntev thiab tsis txhob tawg. Vim tias nws yuav luag tsis tuaj yeem ua tsis tiav, nws tuaj yeem txo tus nqi siv rau TV tshaj tawm thiab muab kev saib zoo tshaj plaws rau cov neeg saib. 

Kev nyab xeeb thiab kev tiv thaiv muaj nuj nqi yog tsim nyog rau ib qho analog TV transmitter. Lub sijhawm ua haujlwm ntev feem ntau ua rau muaj kev puas tsuaj rau lub tshuab. Yog tsis muaj kev nyab xeeb thiab kev tiv thaiv muaj nuj nqi, lub analog TV transmitter tej zaum yuav tawg thiab ua rau kev puas tsuaj rau cov khoom nyob ib ncig ntawm.

Kev tsim cov khoom lag luam zoo yuav tsum xav txog cov neeg siv cov kev xav tau thiab tuaj yeem txhim kho lawv cov kev ua haujlwm zoo. Piv txwv li, ib qho screen meej thiab tsim nyog tsim interface tuaj yeem pab cov neeg ua haujlwm tau txais kev dai ntawm analog TV transmitter ua haujlwm sai. Obviously, nws yog pab tau rau txhim kho kev ua hauj lwm efficiency rau lawv.

Qhov kawg tab sis tsis kawg, koj yuav tsum xaiv lub npe zoo tshaj plaws uas koj ntseeg. Lub hom phiaj tsim nyog tuaj yeem muab koj nrog qhov zoo tshaj plaws analog TV transmitter thiab txhim kho kev lag luam ntawm lub tuam txhab tshaj tawm TV.

Thaum koj xav tau kev pab nrog analog TV transmitter lossis lwm yam khoom siv tshaj tawm hauv TV, nws tuaj yeem muab kev txhawb nqa rau koj raws sijhawm thiab cov lus qhia zoo tshaj plaws. Tsis muaj qhov tsis ntseeg tias lub hom phiaj tsim nyog tuaj yeem txo tus nqi thiab siab ntawm txhua yam rau koj txhua lub sijhawm.

Ib qho analog TV transmitter tuaj yeemtsis txhob xa TV teeb liab yam tsis muaj lwm yam khoom siv tshaj tawm hauv TV. Ntawm no yog cov npe ntawm analog TV tshaj tawm cov khoom siv. Feem ntau, lawv yog:
