Guudmarka

Qaybtan waxaa iska leh UHF Qalabka isgaarsiinta raadiyaha ee band-frequency, Kaas oo gudbin kara maqal iyo muuqaal ilaa xad xaddidan. Loogu talagalay isticmaalka tamarta yar, isku dhafan VCO, PLL, iyo AM broadband muuqaalka muuqaalka, Inta jeer ee qaadaha maqalka ayaa ka dhigaya moduleka mid yar; waxay qabataa xirmo yar oo loox ah, taas oo ku haboon isticmaalayaasha si ay u yareeyaan codsiyada.

Codsiga modulekaan wuxuu kaliya u baahan yahay inuu si fudud ugu xidho sahayda korontada, xadhig maqal ah, iyo fiidiyoow fiidiyoow ah, kuna xidh anteenada si aad u isticmaasho noocyo kala duwan oo qalab elektaroonik ah oo taageera soo dhawaynta TV-ga analoogga ah, oo ay ku jiraan telefoonnada gacanta, TV-yada, laptops, MP4, iyo sawiro dhijitaal ah.

FAQ

Ma ku samayn kartaa gudbiyaha fiidyaha bilaa-waayirka ah ee UHF oo wata cod-weyneeye 10-watt ah?

Hadda ma hayno gudbiyaha fiidiyoowga analogga ah ee leh 10-watt PA. Si fudud maaha in 10-watt PA lagu daro gudbiyaha fiidiyoowga analogga ah ee jira. Waxay u baahan tahay in dib loo habeeyo oo dib loo soo saaro.

Injineerku wuxuu kugula talinayaa inaad tijaabiso gudbiyaha fiidyaha analogga ah marka hore. Ka dib markaad isticmaasho, noo sheeg waxa la hagaajinayo waxaanu ku dari karnaa muunada cusub oo leh 10-watt PA. Markaa ma jeclaan lahayd inaad tijaabiso muunad jira (maya PA) marka hore?
