Ubwino
Maikolofoni opanda zingwe a UHF - njira yotumizira mauthenga yomwe imakhudzidwa kwambiri
Dongosolo la maikolofoni opanda zingwe la UHF ili ndi ukadaulo wapamwamba wa PLL (Phase Locked Loop) wopangira ma frequency, womwe umapereka ma frequency point 100 osinthika, womwe umakhudza ma frequency osiyanasiyana a 460-950MHz, umathandizira kulandira njira ziwiri, komanso kukwaniritsa zosowa za zida zingapo kuti zigwiritsidwe ntchito nthawi imodzi. Dongosololi lili ndi luso labwino kwambiri loletsa kusokoneza. Kudzera mu kapangidwe ka antenna grading ndi ntchito ya "noise locking", limateteza bwino kusokoneza kwa RF kwa chilengedwe, limawonetsetsa kuti chizindikirocho chili choyera komanso chokhazikika, ndipo ndi loyenera zochitika zaukadaulo monga zisudzo, misonkhano, ndi kuphunzitsa.
Ubwino
Lumikizani pafupipafupi mwanzeru
Ntchito yolumikizirana ya infrared ya [IR] dinani kamodzi kokha, dinani kuti mugwirizanitse ma frequency olandila ku transmitter yokha, kuchotsa kusintha kosasangalatsa kwa ma frequency amanja ndikuwonetsetsa kuti ikugwira ntchito bwino komanso molondola.
Kutumiza kokhazikika kwambiri
Kulondola kwa ma frequency okwera kwambiri a ± 0.0005%, kuphatikiza ndi PLL phase-locked loop control, kumathetsa mavuto a ma frequency deviation, ndi ma frequency deviation apamwamba a ± 45KHz, kuonetsetsa kuti palibe kusokoneza ma frequency kapena kuchedwa kwa mawu.
Mtunda wautali ndi kukhulupirika kwakukulu
Mu malo otseguka, mtunda wotumizira uthenga ukhoza kufika mamita 100. Maikolofoni yolumikizira mawu, pamodzi ndi FM modulation, ili ndi mayankho a pafupipafupi a 45Hz ~ 18KHz (± 3dB), ndi kusokonezeka kwathunthu kwa harmonic kwa
