Analogi Multiplexer - ndichiyani?

Ngakhale lero, luso mkulu, maphunziro ndi chidziwitso, osati aliyense amadziwa chimene multiplexer. Mwa njira, kudziwa zimenezi si ankafunika kwambiri, chifukwa chipangizo ichi ntchito zosiyanasiyana yopapatiza, koma kumvetsetsa mawu sakuwupweteka (ngakhale basi chitukuko chonse).

Choncho, multiplexer wotchedwa chipangizo wapadera zida ndi angapo-athandizira - mbendera ndi ulamuliro. Linanena bungwe kwa chipangizo ichi ndi chimodzi chokha. Kufunikira n'chakuti mbendera angathe opatsirana kuti linanena bungwe alionse zolowetsa, amene ntchito kusankha kuphatikiza makamaka wa nyemba.

Okwana pali mitundu iwiri ya chipangizo - akutali analogi ndi digito multiplexer. Mfundo ntchito mitundu ndi chosiyana.

Choncho, chipangizo digito ndi kulowa osankhidwa ndi anakopera kuchepetsa linanena bungwe maganizo. Mtundu zosavuta ntchito, koma si wangwiro ndithu.

Koma analogi multiplexer ndi chipangizo chipangizo kwambiri. Iwo polowera ndi kubwereketsa ogwirizana mwa magetsi, ndi voteji, koma ofooka yekha.

Sitingathe kunena kuti analogi multiplexer, umatchedwanso lophimba ndi, Chili mabomba awiri mwakamodzi: chipangizo ichi angachichite osati ntchito yake, komanso ntchito zonse chibadidwe demultiplexers. Izi zimapangitsa zambiri yabwino ntchito.

Monga mukhoza kudziwa ndi mutu, chipangizo otsiriza ndi wosiyana kotheratu ndi woyamba - izo amatha kupereka chizindikiro kwa linanena bungwe la umodzi wa zolowetsa lapansi. Izi ndi zotheka kuyamika chakuti analogi multiplexer zikugwirizana ndi magetsi.

Koma ntchito ndi chipangizo zimenezi sizingatheke popanda thandizo la makina wothandiza. Pamodzi ndi iye kulamulira dera zofala kwambiri ntchito ndi adiresi ndipo amaloledwa kulowa.

Popeza anachitira ndi chakuti zoterezi analogi multiplexer ndipo icho chiri, inu mukhoza kulankhula za zofunika kwambiri - za tsogolo lake. Ntchito chipangizo ichi kutembenuza bayinare kachidindo - kufanana kwa siriyo ndi mosemphanitsa. Mwachidule, masiwichi zizindikiro.

chipangizo amagwira ntchito chabe: izo Mzimuyo limene zolowetsa ayenera olumikizidwa kwa linanena bungwe ndi woyamba ndi wachiwiri manambala bayinare - iwo ayenera kufanana. chithunzi A ndi zizindikiro adiresi amathandiza munthu kukhala ndi njira yolongosoka zipangizo.

Ndi yosavuta zokwanira, anapatsidwa kuti aliyense multiplexer analogi ali yemweyo zolowetsa chikhazikitso.

Mwachitsanzo, ngati athandizira adilesi kachidindo "00", linanena bungwe mbendera adzakhala wofanana kuti pa athandizira ndi, anatchulidwa ziro, malamulowo "01" akusonyeza woyamba athandizira chizindikiro, ndipo "10" - ndi wachiwiri. owerenga mukhoza kupitiriza.

Tikhonza inu chitsanzo, akulankhula za kufunika kogwiritsa ntchito chipangizo ndi moyo.

Tiyeni tinene nkhani ali ndi anayi zinthu zimene zimafalitsa zizindikiro, ndi chipangizo chamagetsi alipo angathe kukhala "werengani" mmodzi yekha wa iwo. Mu nkhani iyi, ndalama Integrated multiplexer, amene amasankha yekha yoyenera.
