Seo U Lokelang ho se Tseba ka Sehokelo sa Studio Transmitter

Sehokelo sa li-studio-transmitter (kapa STL) se romela molumo le lifitio tsa seea-le-moea kapa seea-le-moea-pono sa seea-le-moea-moea kapa seea-le-moea-pono ho tloha setsing sa khaso ho ea ho sea-le-moea kapa sephatlalatsi sa thelevishene sebakeng se seng.

Hangata sena sea hlokahala hobane libaka tse ntle ka ho fetisisa tsa antenna li holim'a thaba, moo ho hlokahalang tora e khutšoanyane haholo, empa moo studio e sa sebetseng ka ho feletseng. Leha e le libakeng tse bataletseng, setsi sa sebaka se lumelletsoeng sa seteishene se kanna sa se be haufi le sebaka sa studio kapa sebakeng se nang le baahi ba bangata moo transmitter e ka senngoang ke sechaba, kahoo antenna e tlameha ho behoa lik'hilomithara tse 'maloa kapa lik'hilomithara tse' maloa hole.

Ho ipapisitsoe le libaka tse tlamehang ho hokeloa, seteishene se ka khetha sehokelo sa point-to-point (PTP) ho radiofrequency e 'ngoe e khethehileng kapa sehokelo se secha sa marang-rang sa dijithale ka mohala o inehetseng oa T1 kapa E1 (kapa o moholoanyane). Lihokelo tsa seea-le-moea le tsona e ka ba tsa dijithale, kapa mofuta oa khale oa analoge, kapa lebasetere la tse peli. Le lits'ebetsong tsa khale tsa analog, liteishene tse ngata tsa audio le tsa data li ka romelloa ho sebelisoa li-subcarriers.
