Tab sis cov ntaub ntawv mayalsobe khaws cia. Yog li a teeb liab tuaj yeem xa cov ntaub ntawv ( cov ntaub ntawv ), tab sis tsis yog tag nrho cov ntaub ntawv qhia.
Hais txog qhov no, qhov txawv ntawm cov teeb liab thiab cov ntaub ntawv yog dab tsi?
Ib qho analog teeb liab xa data hauv formof wave whereas, digital teeb liab xa cov cov ntaub ntawv binary daim ntawv i.e. hauv daim ntawv ntawm bits. Qhov zoo tshaj plaws piv txwv ntawm ib qho analog teeb liab yog tib neeg lub suab, thiab qhov zoo tshaj plaws piv txwv ntawm digital teeb liab yog kis ntawm datain ib lub computer.
Ib yam li ntawd, lub teeb liab hauv kev sib txuas lus yog dab tsi? A cov ntaub ntawv kev sib txuas lus teeb liab isanymodulatedelectromagnetic yoj - lossis digital pulse - dhau qhov ntawd cov ntaub ntawv yog kis los ntawm ib qho chaw mus rau lwm qhov inanetwork. Cov no teeb liab muaj qee qhov yooj yim thiab ntsuas tau cov yam ntxwv uas cuam tshuam nrog lawv, uas tseem hu ua lawv cov yam ntxwv.
Yog li, dab tsi yog cov ntaub ntawv thiab teeb liab hauv computer network?
Cov ntaub ntawv Kev sib txuas lus thiab Kev sib koom tes : Dataand Signals . Ntsiab lus: Lus qhuab qhia. Cov ntaub ntawv tuaj yeem ua analog lossis digital. Lub sij hawm analog cov ntaub ntawv hais txog cov ntaub ntawv uas txuas ntxiv; digital cov ntaub ntawv xa mus rau cov ntaub ntawv uas muaj discrete xeev. Analog cov ntaub ntawv takeoncontinuousvalues.
Lub teeb liab thiab hom teeb liab yog dab tsi?
Feem ntau peb ntsib ob hom teeb liab . Analogand Digital. Thiab lwm yam theoretical teeb liab xws li sin, cos..etc. A digital teeb liab yog a teeb liab uas yog siv torepresent cov ntaub ntawv raws li ib theem ntawm discrete muaj nuj nqis; atanygiven lub sij hawm nws tsuas tuaj yeem siv rau ntawm ib qho ntawm cov nqi tsis kawg.
