Equalizer

Equalizer ndi chipangizo chamagetsi chomwe chimatha kusintha magawo osiyanasiyana amagetsi amagetsi kuti athetse kupotoza komwe kumachitika chifukwa cha ma siginecha omwe amafalitsidwa kudzera munjira zina. M'makina olankhulirana, cholinga chachikulu chogwiritsira ntchito kufananitsa ndikuchotsa kusokoneza kwa zizindikiro ndikubwezeretsanso ma sign omwe atayika.
Ma radio frequency equalizers amagwiritsidwa ntchito kwambiri pankhani yolankhulirana, makamaka kuti athetse vuto la kusokonekera kwa ma siginecha komwe kumachitika chifukwa cha kuchepa kwa njira.

Zotsatirazi ndi zina zofananira za RF pazolumikizana:

1.Kulankhulana opanda zingwe: Mwa kusintha matalikidwe ndi gawo la chizindikiro kuti apereke malipiro a kutha kwa njira, mapeto olandira amatha kulandira ndikuzindikira chizindikirocho molondola.
2.Digital TV: Zizindikiro za Digital TV zimafuna kusintha kwakukulu ndi zosefera, monga DFT, IDFT, FEC code, VSB, ndi zina zotero. Njirazi zingayambitse kusokoneza nthawi zonse ndi maulendo afupipafupi. Zofananira za RF zimatha kuthana ndi zosokoneza izi posefa ndikusintha matalikidwe ndi gawo, kulola owonera kuwona zithunzi zomveka bwino.
3. Zida zoyankhulirana: Zofananira za RF zimagwiritsidwa ntchito kwambiri pazida zoyankhulirana, monga masiteshoni oyambira, radar, satellite kulankhulana, ndi zina zotero. Ma frequency ofananira a wailesi angathandize kuwongolera kudalirika komanso kukhazikika kwa kulumikizana, ndipo amatha kuchepetsa kuchuluka kwa zolakwika ndi kugwiritsa ntchito mphamvu zamagetsi mu kufalitsa chizindikiro.

QualwaveInc. imapereka ma frequency osiyanasiyana a DC ~ 40GHz equalizer, muyeso woyezera ndi 1dB mpaka 25dB, kutayika koyikirako ndi 1dB ~ 8.5dB, mawonekedwe oyimirira ndi 1.04dB ~ 2dB, mitundu yolumikizira ndi SMA ndi 2.92mm, nthawi yoperekera nthawi zambiri amakhala masabata 2-4. Ndipo chofananira chochokera ku Qualwaves Inc. ndi chaching'ono, chosavuta kukhazikitsa ndipo chimafunikira malo osungira ochepa. Tekinoloje yathu yofananira ndi yokhwima, ndipo imagwiritsidwa ntchito kwambiri pamapulogalamu ambiri.
Ngati kasitomala ali ndi zosowa zina, tikhoza kusintha.
Takulandirani makasitomala kuti mufunse. Tidzapereka ntchito yofunda komanso yaukadaulo.
