Digital Multiplexer: description, ujeedada, noocyada

multiplexer A digital waa qalab macquul ah oo isku jira oo waxaa loogu tala galay gudbinta gacanta xogta ka dhowr ilo xog si channel wax soo saarka ah. Dhab ahaantii, qalab this waa daaro mawqifyada digital badan. Waxaa soo baxday in biiro waa calaamadaha aqbasho multiplexer digital galay line a soo saarka hal.

qalab waxa uu leeyahay saddex kooxood oo gashiga:

• cinwaanka, code binary oo go'aamisa macluumaadka talooyin ku xiran yahay in wax soo saarka;
• macluumaad;
• saamaxdo (gating).

The soo saaray wareeggeedii dhafan digital multiplexer 16 leeyahay gashiga macluumaadka ugu badan. Haddii unugga saadaaliyey u baahan yahay xaddi weyn, taasoo qaabka lagu dhisay ee loo yaqaan geed multiplexer dhowr chips.

multiplexer Digital loo isticmaali karaa ereygu wuxuu ahaa ee ficil unit kasta oo macquul ah, taas oo si xooga yaraynaysaa tirada wareeggeedii loo isticmaalo in xubno ka macquulka ah.

multiplexers Rules qalabka Avv ku salaysan:

• map Karnaugh waxaa dhisay function wax soo saarka (sida ay qiyamka hawlaha variable);
• la doorto si isticmaalka Bannaanka multiplexer ah;
• shareeraysaa furta oo dhisay, oo waa inay u dhigmaan si loo isticmaalo by multiplexer ah;
• furta oo keentay waa in lagu soo rogay on map Karnaugh ah;
• intaas ka qaadeen function yaraynta si gooni gooni ah oo dhinac kasta oo isdiyaarin kara,
• ku saleysan yareeyo natiijada loo baahan yahay in la dhiso Bannaanka.

Fikradda hadda in ay ku dhaqmaan. Ka fikir meesha ka codsatay qalabka sida.

multiplexers dabacsan waxaa loo isticmaalaa guud ahaan durdurrada digital (hoose) ee heerka a of 2048 kbit / s ah signal analog (speech), iyo interfaces digital xogta cross-xirmaan channels electronic at 64 kbit / s, gudbinta durdur digital ah IP network / Ethernet iyo diinta seylaanyenta line iyo kalagoysyada jirka.

Iyada oo qalab noocan oo kale ah la isugeeyey kartaa ilaa 60 (in lagu daydo qaar ka mid ah, tiradaasi waxay noqon kartaa in ka badan) Joojinta analog in 1 ama 2 E1 128 ama nooc macmiilka afar E1. Sida caadiga ah, ee Joojinta PM analog taag khadadka isagoo seylaanyenta band ama nidaamka digniinta waxaa fuliyey on channel gaar ah. channels codka waxaa la Tifaftirayaasha kartaa in 32 ama 16 kbit / s per channel, waxa uu u adeegsanayaa koodh ADPCM ah.

multiplexers dabacsan oggolaadaan in aad si ay u isticmaalaan la xidhiidha multicast, ie siin calaamadaha ka mid ka mid ah channels digital ama analog on a yar kuwa kale. Inta badan loo isticmaalaa qeybinayay barnaamijyada raadiyaha mar dhowr goobood oo kala duwan.

multiplexers indhaha - waa qalab loogu talagalay in lagu durdurro xogta la isticmaalayo alwaaxdii saqafka haysay iftiinka kala duwan Ilodanimada inayan ama wajiga shaqeeyaan shabaggeedii iyo Milanello. Faa'iidooyinka qalabka sida ka mid ah adkeysiga, amaanka farsamo, ilaalinta jabsiga macluumaadka la isugu gudbiyo.
