Kingtone yihariye inshuroVHFUmuyoboroBi Amplifier (BDA)ni ikiguzi cyiza kandi cyizewe cyagenewe kwaguka no kunoza aho ikwirakwizwa ryaVHFsisitemu y'itumanaho.Umuyoboro Uhitamo BDAs ituma uyikoresha yongerera gusa abatwara ibyifuzo mubyerekezo byombi, kuzamura no kumanuka.Guhitamo umuyoboro birashobora gutegurwa muburyo bwa RS 232 cyangwa kure ukoresheje Modem cyangwa RJ45.
ICYITONDERWA
Icyitonderwa 1: Sisitemu isohoka imbaraga nigikorwa cyumubare wabatwara ibyabaye kuri sisitemu, urwego rwibimenyetso rwabatwara s kugeza kuri
sisitemu yo kuzamura ibimenyetso, inyungu za PA, hamwe no kwinjiza igihombo cyayunguruzo muri sisitemu yuburyo bubiri.
Icyitonderwa 2: Sisitemu Urusaku Igishushanyo nigiteranyo cya amplifier NF hamwe nigihombo cyo kuyungurura mbere ya amplifier.Akayunguruzo gutakaza igihombo biterwa na
ubugari bwa passband kuri uplink frequency, ubugari bwa passband kumurongo wamanutse, hamwe no guhagarara hagati yabo.
Kubaho kwa VHF Gusubiramo BDA itanga sisitemu yitumanaho rya interineti hamwe numuyoboro munini utwara, kubera ko ubwiyongere bwagutse burenze kurubuga.Porogaramu zisanzwe zuyu murongo wa booters ni ibintu byo murugo nka tunel, inyubako, metero, hamwe na sisitemu yo hanze nka stade, icyaro hamwe nicyaro cyumujyi.Kuberako aribintu bibiri byibikoresho, urashobora rero kuzigama ikiguzi cyo gukuba kabiri ibiryo.
