Qhov zoo ntawm ib analog kaw kaw lus yog tus tsis muaj aliasing distortion thiab quantization nrov; tus dav dynamic ntau yam; thiab kev ua tau zoo nyob rau hauv cov xwm txheej overload. Cov tshuab digital, lub sijhawm no, muaj kev kaw suab zoo dua thiab kev sib koom ua ke yooj yim dua rau cov khoos phis tawj ntawm tus kheej thiab cov ntawv thov software.

Ib yam li ntawd, tej zaum koj yuav nug, dab tsi yog qhov zoo ntawm cov teeb liab analog?

Qhov zoo:? Qhov zoo ntawm cov teeb liab analog yog infinite cov ntaub ntawv. ? Qhov ceev yog ntau dua. ? yooj yim ua. ? Qhov tsis zoo:? Tsis xav suab nrov hauv kev kaw cia.

Ib tug kuj yuav nug, dab tsi yog qhov zoo thiab qhov tsis zoo ntawm kev siv cov cim digital es tsis txhob siv cov analog xa cov ntaub ntawv? Cov nyhuv ntawm distortion, suab nrov, thiab cuam tshuam yog tsawg dua nyob rau hauv digital signals raws li lawv tsis tshua muaj kev cuam tshuam. Digital circuits yog txhim khu kev qha. Digital circuits yog ib qho yooj yim los tsim thiab pheej yig dua analog circuits. Hardware Implementation nyob rau hauv digital circuits, yog hloov tau ntau dua analog.

Ntawm no, dab tsi yog qhov zoo ntawm kev siv cov teeb liab digital tshaj cov analogues?

Muaj ntau qhov zoo siv cov teeb liab digital tshaj qhov teeb liab analog

• Cov teeb liab digital muaj kev nyab xeeb dua, thiab lawv tsis raug puas los ntawm lub suab nrov.
• Cov teeb liab no siv tsawg bandwidth.
• Lawv tso cai rau cov teeb liab kis tau los ntawm qhov ntev.
• Cov teeb liab digital muaj qhov sib kis ntau dua.

Dab tsi yog teeb meem ntawm kev xa cov teeb liab analog?

Suab nrov thiab teeb liab degradation yog ob qho teeb meem yooj yim hauv kev sib kis cov teeb liab analog. Kev tswj tsis tau cov txheej txheem cuam tshuam. Cov teeb liab coj tuaj yeem khaws ob hom sab nraud suab nrov - hom hom thiab ib txwm hom.
