Muri iki kiganiro ngiye kuvuga kubijyanye na Moderi ya sisitemu yitumanaho muburyo burambuye harimo ibice byabo 5, (1) Inkomoko ya code na decoding, (2) Encoding na decoding yimiyoboro, (3) Encryption and decryption, (4) Modulation Digital and demodulation, (5) Guhuza. Reka twibire cyane…
Uburyo bw'itumanaho rya Analog
Uburyo bw'itumanaho rya sisitemu
(1) Inkomoko ya code na decoding:
Ibikorwa bibiri by'ibanze: kimwe ni ukunoza imikorere yo kohereza amakuru, ni ukuvuga kugabanya umubare wibimenyetso kugirango ugabanye igipimo cyibimenyetso ukoresheje tekinoroji yo gukusanya amakuru. Icyakabiri nukuzuza analogue / digital (A / D) guhinduka. Nukuvuga ko, mugihe amakuru yamakuru atanga ibimenyetso bya analogue, inkomoko ya kodegisi iyihindura mubimenyetso bya digitale kugirango tumenye ihererekanyabubasha rya signal ya analogue.
(2) Encoding na decoding yimiyoboro:
Imikorere: Gukora kugenzura amakosa. Ibimenyetso bya digitale birashobora guterwa n urusaku nandi makosa mugihe cyo kohereza. Kugirango ugabanye amakosa, umuyoboro wa kodegisi hamwe nibimenyetso byamakuru byongeweho byongeramo ibice byo kurinda (ibimenyetso byubugenzuzi) ukurikije amategeko amwe kugirango bibe byitwa "kode yo kurwanya interineti." Umuyoboro wa decoder kumyakire yanyuma ya decode ishingiye kumategeko atandukanye naya yoherejwe. Irasanga amakosa cyangwa ayakosora, bigatuma sisitemu yitumanaho irushaho kwizerwa.
(3) Encryption and decryption:
Kugirango umenye umutekano wamakuru yatanzwe, urutonde rwa digitale rwandujwe rwakozwe muburyo bwimbitse - ni ukuvuga ijambo ryibanga ryongeweho. Iyi nzira yitwa encryption. Kugarura amakuru yumwimerere ni decryption.
(4) Guhindura imibare na demodulation:
Guhindura muburyo bwa digitale: Ikirangantego cyibimenyetso bya digitale ya baseband yimuriwe kumurongo mwinshi kugirango ikore ikimenyetso cya bande ikwiranye numuyoboro. Mugihe cyo kwakirwa, ibimenyetso bya baseband ya digitale birashobora kugarurwa hakoreshejwe demodulation ihujwe cyangwa demodulation idahuje.
(5) Guhuza:
Guhuza: Nugukomeza ibimenyetso kumpande zombi za transceiver bigahuzwa mugihe, kandi nibisabwa kugirango tumenye imikorere itunganijwe, yuzuye, kandi yizewe ya sisitemu yitumanaho rya digitale.
Ngiyo ngingo kuri "Model Itumanaho Model" yazanwe na Shenzhen HDV phoelectron Technology Co., Ltd. twizere ko iyi ngingo ishobora kugufasha kongera ubumenyi. Usibye iyi ngingo niba ushaka ibikoresho byiza bya fibre itumanaho ibikoresho bya sosiyete ushobora gutekerezaibyerekeye twe.
Shenzhen HDV phoelectron Technology Co., Ltd.ni uwukora ibicuruzwa byitumanaho. Kugeza ubu, ibikoresho byakozwe bitwikiriyeUrukurikirane rwa ONU, icyiciro cya optique, Urukurikirane rwa OLT, naurukurikirane. Turashobora gutanga serivisi yihariye kubintu bitandukanye. zishobora gukoreshwa muburyo butandukanye Gutanga serivise ihanitse yujuje ubuziranenge ukurikije ibyo abakoresha bakeneye.
