Multiplexing pib hauv xov tooj hauv xyoo 1870, thiab tam sim no tau siv dav hauv kev sib txuas lus. Hauv xov tooj, George Owen Squier tau txais txiaj ntsig nrog kev txhim kho cov xov tooj sib txuas hauv xyoo 1910.
Leej twg tsim multiplexing?
French visionary engineer Jean-Maurice-Émile Baudot yog tus uas tsim lub sij hawm faib multiplexing thiab txhawb kev sib txuas lus zoo rau yav tom ntej.
koj txhais li cas los ntawm multiplexer?
Hauv electronics, multiplexer (los yog mux; spelled qee zaum ua multiplexor), tseem hu ua a cov ntaub ntawv xaiv, yog ib qho khoom siv uas xaiv ntawm ob peb analog lossis digital input signals thiab xa mus rau qhov kev xaiv nkag mus rau ib txoj kab tso zis. Kev xaiv yog qhia los ntawm ib qho kev sib cais ntawm cov khoom siv digital hu ua kab xaiv.
Lub hom phiaj ntawm kev sib tw yog dab tsi?
Lub hom phiaj ntawm kev sib txuas lus yog txhawm rau ua kom cov teeb liab kis tau zoo dua ntawm kev sib txuas lus sib txuas, yog li txo tus nqi sib kis. Ib lub cuab yeej hu ua multiplexer (feem ntau luv luv rau "mux") muab cov tswv yim tawm tswv yim rau hauv ib lub teeb liab.
hom kev sib txuas lus twg tau siv xov tooj?
Lub Quadruplex xov tooj yog ib hom xov tooj hluav taws xob uas tso cai rau tag nrho plaub qhov kev sib cais kom xa thiab tau txais ntawm ib lub xaim tib lub sijhawm (ob lub teeb liab hauv txhua qhov kev taw qhia). Quadruplex telegraphyyog li siv ib daim ntawv ntawm multiplexing.
