Analog Multiplexer - yintoni na?

Nanamhlanje, ubuchwepheshe phezulu, imfundo kunye nolwazi, asinguye wonk 'umntu uyazi into a multiplexer. Hi ndlela leyi, olu lwazi kukuba akufuneki ukuba kakhulu kunene, kuba le ifowuni isetyenziswa kuluhlu exineneyo, kodwa ukuqonda eli binzana ayinakulimaza (nokuba nje kuphuhliso).

Ngoko ke, lo multiplexer ebizwa isixhobo ekhethekileyo exhotyiswe multiple-igalelo - umqondiso kunye nolawulo. Imveliso esuka kule fowuni enye kuphela. Ukubaluleka kukuba umqondiso nga idluliselwe imveliso kuyo nayiphi na kwezi zimvo, nto leyo isetyenziselwa khetha indibaniselwano othile la mandla.

Xa iyonke kukho iintlobo ezimbini isixhobo - analog ekwanti kunye multiplexer digital. Umgaqo ukusebenza kwezi ntlobo zahluke ngokupheleleyo.

Ngenxa yoko, kwiphakati lwedijithali kunye ungeno ekhethiweyo zikhutshelwa kwi amanqanaba kwimveliso logic. Olu hlobo Kulula kakhulu ukuyisebenzisa, kodwa hayi ncam abafezekileyo.

Kodwa analog multiplexer sisixhobo nobunzima kakhulu. It owongozelelweyo iplagi oxhulumene ngokusebenzisa umbane, kunye ombane, kodwa wavuma kuphela.

Asikwazi athi multiplexer analog, nezaziwa ngokuba uneswitshi, ludibanisa izixhobo ezimbini kwaoko: esi sixhobo ukwenza nje kuphela umsebenzi walo, kodwa yonke imisebenzi ezendeleyo demultiplexers. Oku kwenza kube lula ukuba asebenzise ngaphezulu.

Njengoko xelela esithi, isixhobo lokugqibela sisichasi ngqo ukuya yokuqala - iyakwazi ukuba angadlulisela umqondiso ovela imveliso omnye ulime. Oku Bulelani kunokwenzeka ukuba yokuba multiplexer analog kanga kuwo ngombane.

Kodwa ukusebenza nale fowuni kunokwenzeka ngaphandle koncedo koomatshini abangabancedani hayi. Kunye naye ezininzi eziqhele ukusetyenziswa yesekethe ulawulo kunye nedilesi kunye kuvunyelwa ukuba bangene.

Ukuba iyitshinizele nesibakala sokuba umntu onjalo multiplexer analog yintoni na, uyakwazi ukuthetha malunga ibalulekileyo - ikamva lakhe. Sebenzisa le divaysi ukuguqula ikhowudi yokubini - onxusene alcohol lezibuko ne vice. Ngamafutshane, oku sokuyivula imiyalezo.

Esi sixhobo isebenza nje: oko ichaza ukuba izakuba ngowuphi ngamagalelo kufuneka adityaniswe kwi imveliso yi amanani yokuqala neyesibini lokubini - kufuneka ifane. Idayagram ne dilesi codes kunceda umntu ukuba ungagcina umkhondo izixhobo.

Kuyinto elula ngokwaneleyo, njengoko nayiphi multiplexer analog unalo igalelo elifanayo isiqu.

Umzekelo, ukuba igalelo idilesi ikhowudi "00", uphawu output iya kulingana naleyo kwi igalelo, otyunjwe zero, ikhowudi "01" ibonisa uphawu igalelo yokuqala, yaye "10" - kunye wesibini. Umfundi uqhubeke.

Sinako bakunike umzekelo, ukuthetha malunga imfuneko yokusebenzisa esi sixhobo ebomini.

Masithi umenzi ezine izinto adlulisela imiqondiso, kwaye sixhobo ekhoyo kunokuba "funda" enye kuphela kubo. Kulo mzekelo, malini multiplexer ehlanganisiweyo, aya kuyinyula omnye efanelekileyo kuphela.
