Analog Multiplexer - kuyini?

Ngisho nanamuhla, ngobuchwepheshe, imfundo nolwazi, akubona bonke uyazi ukuthi Multiplexer. By the way, lolu lwazi iwukuba ufundelwe ayidingeki ukuthi kakhulu, ngoba le divayisi isetshenziswa ibanga ewumngcingo, kodwa qondani okuyintando leli gama akusho ubuhlungu (ngisho noma nje ukuthuthukiswa jikelele).

Ngakho, Multiplexer ngokuthi idivayisi ekhethekile ifakwe amaningi-okokufaka - isignali nokulawula. Lokukhipha kusukela kule divayisi munye kuphela. Ukubaluleka Kuyaphawuleka ukuthi isiginali angadluliselwa okukhiphayo kunoma imibono, okuyinto olusetshenziswa ukukhetha inhlanganisela ethile ye pulses.

Sekukonke kunezinhlobo ezimbili idivayisi - analog aqhelelene futhi Multiplexer digital. Umgomo we operation zalezi zinhlobo bahluke ngokuphelele.

Ngakho, ngo-idivayisi digital ne okufakiwe kukhethiwe ikopishelwe amazinga okukhipha logic. Lolu hlobo Kulula kakhulu ukusebenzisa, kodwa hhayi ngempela ephelele.

Kodwa-analog Multiplexer yidivayisi ezingcono. It Inlet futhi esidayisa axhunyiwe esebenzisa ugesi, nge voltage, kodwa wavuma kuphela.

Asinakusho ukuthi Multiplexer analog, okubhekiselwa kuzo nangokuthi inkinobho, ihlanganisa amadivayisi amabili ngesikhathi esisodwa: kule divayisi ongenza umsebenzi hhayi kuphela ayo, kodwa futhi yonke imisebenzi ehambisana demultiplexers. Lokhu kwenza kube zibelula ukuyisebenzisa.

Njengoba ungakwazi ukutshela ngesiqu, idivayisi zokugcina kuphambene ngqo ngowokuqala - ke uyakwazi adlulisele isiginali kusuka ekhishwa omunye izidingo. Lena sibonga kungenzeka iqiniso lokuthi Multiplexer analog uxhuma nabo ugesi.

Kodwa ukusebenza kule divayisi akunakwenzeka ngaphandle kosizo imishini elisizayo. Ndawonye kanye naye ngokuvamile ezisetshenziswa ukulawula wesifunda ikheli kanye okuvunyelwa ukuba kungene.

Njengoba asebenzelana ngayo yokuthi onjalo Multiplexer analog ukuthi kuyini, ungakwazi ukukhuluma ebaluleke kakhulu - ikusasa lakhe. Sebenzisa le divayisi ukuguqula ikhodi kanambambili - parallel serial, noHezekeli. Kalula nje, yingoba sekuqalile amasignali.

Le divayisi isebenza ukumane: inquma ukuthi yiziphi imibono kumele exhunywe kwi-okuphumayo by izinombolo lokuqala nelesibili kanambambili - kufanele ukufanisa. Umdwebo nge amakhodi ikheli kusiza umuntu ukuba lokhozi amadivaysi.

Kuyinto elula ngokwanele, uma kubhekwa ukuthi iyiphi Multiplexer analog has okufanayo isiqu okokufaka.

Ngokwesibonelo, uma ufake ikheli le-kuyinto ikhodi "00", isiginali okukhipha kuyoba ulingana ukuthi ngesikhathi input, okhethwe zero, ikhodi "01" kubonisa isignali okufakwayo ngowokuqala, futhi "10" - ne lesibili. Umfundi ungaqhubeka.

Singagcina ngokubu- ukukunika isibonelo, ukhuluma ngesidingo ukusebenzisa le divayisi empilweni.

Ake sithi isihloko lelinetintfo ezinye ezine adlulisa amasignali, futhi lisebenze ekhona kungaba "funda" kuphela omunye wabo. Kulokhu, Kubiza Multiplexer ehlangene, okuyinto ekhetha umuntu okulungile.
