Equalizer

Equalizer ke sesebelisoa sa elektroniki se ka fetolang likarolo tse fapaneng tsa maqhubu a matšoao a motlakase ho felisa ho khopama ho bakoang ke matšoao a fetisoang ka liteishene tse itseng. Litsamaisong tsa puisano, sepheo sa mantlha sa ho sebelisa tekano ke ho felisa tšitiso ea matšoao le ho khutlisa matšoao a lahlehileng.
Li-equalizer tsa maqhubu a seea-le-moea li sebelisoa haholo lefapheng la puisano, haholo-holo ho rarolla bothata ba ho sotha ha matšoao ho bakoang ke ho fifala ha mocha.

Tse latelang ke tse ling tsa lits'ebetso tsa li-equalizer tsa RF lefapheng la puisano:

1. Puisano e se nang mohala: Ka ho lokisa amplitude le mohato oa pontšo ho lefella ho fela ha mocha, qetello ea ho amohela e ka amohela le ho khetholla letšoao ka nepo.
2.Digital TV: Lipontšo tsa TV tsa Digital li hloka liphetoho tse ngata le mekhoa ea ho hloekisa, e kang DFT, IDFT, FEC code, VSB, joalo-joalo Mekhoa ena e ka baka ho khopama libakeng tse peli tsa nako le khafetsa. Li-equalizer tsa RF li ka sebetsana le likhothaletso tsena ka ho sefa le ho lokisa amplitude le phase, ho lumella bashebelli ho bona litšoantšo tse hlakileng.
3. Thepa ea puisano: Li-equalizer tsa RF li sebelisoa haholo lisebelisoa tsa puisano, tse kang liteishene tsa motheo, radar, puisano ea sathelaete, joalo-joalo Li-equalizer tsa maqhubu a seea-le-moea li ka thusa ho ntlafatsa botšepehi le botsitso ba puisano, 'me li ka fokotsa sekhahla sa phoso le tšebeliso ea matla a phetisetso ho phetiso ya pontsho.

QualwaveInc. e fana ka mefuta ea maqhubu a DC ~ 40GHz e leka-lekaneng, tekanyo ea tekanyo ke 1dB ho 25dB, sebaka sa tahlehelo ea ho kenya ke 1dB ~ 8.5dB, leqhubu le emeng ke 1.04dB ~ 2dB, mefuta ea li-connector ke SMA le 2.92mm, nako ea ho fana ka nako. hangata ke libeke tse 2-4. Mme tekanyo e tsoang ho Qualwaves Inc. e nyane, e bonolo haholo ho e kenya mme e hloka sebaka se senyenyane sa polokelo.
