Isilinganisi

I-Equalizer iyisisetshenziswa se-elekthronikhi esingalungisa izingxenye ezihlukahlukene zefrikhwensi yamasignali kagesi ukuze kuqedwe ukuhlanekezela okubangelwa amasignali asakazwa ngamashaneli athile. Ezinhlelweni zokuxhumana, inhloso enkulu yokusebenzisa ukulinganisa ukuqeda ukuphazamiseka kwezimpawu nokubuyisela amasignali alahlekile.
Izilinganisi zefrikhwensi yomsakazo zisetshenziswa kakhulu emkhakheni wezokuxhumana, ikakhulukazi ukuxazulula inkinga yokuhlanekezelwa kwesignali okubangelwa ukufiphala kwesiteshi.

Okulandelayo ezinye izinhlelo zokusebenza zezilinganisi ze-RF emkhakheni wezokuxhumana:

1.Ukuxhumana okungenantambo: Ngokulungisa i-amplitude nesigaba sesiginali ukuze kunxephezele ukufiphala kwesiteshi, isiphetho sokwamukela singathola futhi sikhiphe isignali ngendlela efanele.
I-2.I-TV ye-Digital: Amasignali we-TV yedijithali adinga izinguquko eziningi kanye nezinqubo zokuhlunga, njenge-DFT, IDFT, ikhodi ye-FEC, i-VSB, njll. Lezi zinqubo zingabangela ukuhlanekezela kuzo zombili izizinda zesikhathi nemvamisa. Izilinganisi ze-RF zingamelana nalokhu kuhlanekezelwa ngokuhlunga nokulungisa ubude nesigaba, okuvumela ababukeli ukuthi babone izithombe ezicacile.
3. Imishini yokuxhumana: Izilinganisi ze-RF zisetshenziswa kakhulu ezintweni zokuxhumana, njengeziteshi eziyisisekelo, i-radar, ukuxhumana ngesathelayithi, njll. Izilinganisi zefrikhwensi yomsakazo zingasiza ukuthuthukisa ukwethembeka nokuzinza kokuxhumana, futhi zinganciphisa izinga lamaphutha kanye nokusetshenziswa kwamandla okudlulisela ukudluliswa kwesignali.

QualwaveI-Inc. ihlinzeka ngobubanzi befrikhwensi ye-DC ~40GHz isilinganisi, ububanzi bokulinganisa bungu-1dB ukuya ku-25dB, ububanzi bokulahlekelwa bokufaka ngu-1dB~8.5dB, ububanzi begagasi obumayo bungu-1.04dB~2dB, izinhlobo zezixhumi ziyi-SMA kanye no-2.92mm, isikhathi sokulethwa. ngokuvamile amaviki angu-2 ~ 4. Futhi isilinganisi esivela ku-Qualwaves Inc. sincane, kulula kakhulu ukusifaka futhi sidinga indawo yokugcina encane kakhulu. Ubuchwepheshe bethu bokulinganisa buvuthiwe, futhi busetshenziswa kabanzi ezinhlelweni eziningi.
Uma ikhasimende linezidingo ezengeziwe, singakwazi futhi ukwenza ngendlela oyifisayo.
Siyakwamukela amakhasimende ukuze ubuze. Sizohlinzeka ngenkonzo efudumele neyochwepheshe.
