Kev sib piv ntawm Analog teeb liab thiab Digital Signal
Seb qhov teeb meem zoo li analog yog zoo los yog cov teebmeem digital zoo, coob tus neeg yuav hais cov teeb meem digital, tab sis vim li cas lawv lub teeb meem zoo? Tom qab ntawd muaj ntau heev tsawg tus neeg uas tsis tuaj yeem teb nws, raws nraim analog thiab digital signals.
Qhov zoo thiab qhov tsis zoo yog dab tsi?
Qhov zoo ntawm analog kev sib txuas lus yog intuitive thiab yooj yim rau kev siv, tab sis muaj ob lub ntsiab lus tseem ceeb.
1) Tsis pub leejtwg paub
Kev sib txuas lus sib txuas lus, tshwj xeeb tshaj yog microwave kev sib txuas lus thiab kev sib txuas lus sib tw, yog yooj yim eavesdropped. Tsuav tau txais qhov teeb liab analog, nws yog qhov yooj yim kom tau txais cov lus sib txuas lus.
2) tsis muaj zog tiv thaiv kev cuam tshuam
Thaum lub sij hawm kis tau tus kab mob, lub teeb liab hluav taws xob yuav raug ntau yam nrov ntawm sab nraud thiab txoj kev sib txuas lus. Nws yog qhov nyuaj cais cov suab nrov thiab lub teeb liab, uas ua rau kev sib txuas lus zoo zoo nruj. Ntau qhov kab
Ntev, qhov tsub zuj zus ntawm suab nrov ntau dua.
3) Tsis haum rau kev ncua ntev
Cov kis tau zoo
1) Ntxiv kev ruaj ntseg ntawm kev sib txuas lus.
2) Txhim kho kev muaj peev xwm cuam tshuam.
3) Tsim kom muaj kev sib tiv tauj digital network. Tom qab sijhawm sib faib, kev sib kis thiab kev sib pauv yuav koom ua ke, thiab muaj kev sib tiv tauj digital network.
4) Haum kev kis tau ntev
Vim hais tias cov teeb liab tshwm sim tuaj yeem tsim kho los ntawm shaping thiab qhov kev txiav txim siab thaum lub sij hawm kis tau tus mob, nws muaj peev xwm paub tau lub ncej ntawm high-quality ntev-kis sib txuas nrog tsis muaj suab nrov tsoo thiab tsis muaj teebmeem ntawm nonlinear.
Txoj kev kis cov kab mob kis tau yooj yim thiab kev sib kis tsawg heev ua rau kev sib tham ntawm cov kev sib txuas lus tau. Piv nrog cov tsoos analog optical kis las, cov yeeb yaj duab optical kis tau tus mob muaj cov nram qab no zoo kawg li:
1) Cascading, raws li qhov kev ncua deb, SNR teeb liab-rau-nrov ratio tsis txo.
2) Vim hais tias nws yog ib txoj kev sib txuas lus, nws txais cov kev ua yuam kev ntawm kev ua yuam kev, uas muaj kev ruaj siab thiab kev ntseeg siab.
3) Thaum cov teeb meem sib tshooj sib txig sib txig ib zaug, cov sij hawm digital multiplexing (TMD) siv, uas tsis tsim kev cuam tshuam kev sib deev thaum lub sij hawm analog.
4) Zoo stability, siab adaptability, yooj yim los tswj thiab kho dua li analog kis cev.
5) Nws yog ib qho yooj yim kom paub ntau qhov muaj peev xwm kis tau zoo thiab raug nyiaj tsawg.
6) Nrog rau cov tsis muaj kev tiv thaiv, cov teeb liab duab zoo siab heev thiab ncav lub phiajxwm.
Hauv kev sib kis, xws li kev soj ntsuam cov video, cov ntaub ntawv sib txuas lus, thiab lwm yam, yeej ua tiav los ntawm cov twj paj nruag optical transceiver, thiab feem ntau siv hauv video keb soj ntsuam yog cov khoom siv sib txuas xws li video optical transceiver.
ECON TECH stepper tsav, hybrid servo tsav, multi-axis kaw voj stepper tsav yog tag nrho cov thov rau cov kev sib txuas lus, zoo heev pab txoj kev ua tau zoo ntawm cov khoom stepper.
