Kev txhais tau tias ntawm cov ntaub ntawv tiv thaiv

Kev txoj kev ntawm cov ntaub ntawv tiv thaiv nyob ib qho tseem ceeb qhov chaw nyob rau hauv qhov kev siv ntawm kev ruaj ntseg cai nyob rau hauv tej lub koom haum los yog ib qho tseem ceeb cov khoom. Cov nyiaj no yog siv los nrhiav cov hom kev kawm mus nyiag ntaub ntawv, uas yog tej zaum kuj ntsia ntawm qhov chaw cais tawm ntawm qhov chaw zov thaum lub sij hawm cov kev sib khom los yog ib qho tseem ceeb lub rooj sib tham los tiv thaiv kev sib txuas lus thiab technology siv rau lub ua ntawm cov ntaub ntawv.

Kev txhais tau tias ntawm cov ntaub ntawv tiv thaiv: xaiv ntawm cov khoom

Cov teeb meem muaj feem xyuam rau cov kev xaiv ntawm cov khoom tsim los tiv thaiv koj lub koom haum, yuav tsum tau mus nrog zoo saib xyuas. Koj yuav tsum muab los xav thaum xaiv ib tug xov tooj cua generator, ua pa nrov cav, hu xov tooj kab tiv thaiv pab kiag li lawm, thiab lwm yam khoom txaus yam uas tseem ceeb heev: lawv txawj thiab weaknesses, ib tug kev sib nrig sib cawv rau txhua lwm yam, raws li tau zoo raws li ib tug ntau ntawm cov lwm yam. Siv tshwj xeeb ntaub ntawv, koj yuav tsis tau tsuas yog tau ntsib nrog rau cov spectrum ntawm kev txiav txim ntawm xws khoom, tab sis kuj los mus txiav txim zaum kawg xaiv.

Kev txhais tau tias ntawm cov ntaub ntawv tiv thaiv cov chaw

Yuav kom tiv thaiv cov chaw yog heev nquag siv ntau hom kev acoustic thiab vibro-acoustic suab nrov pa phem. Lawv lub ntsiab lub hom phiaj yog los mus tiv thaiv hais lus ntaub ntawv, uas muaj peev xwm muab daim nyob rau hauv lub chav tsev, los mloog nrog ntau hom stethoscopes, acoustic microphones, infrared thiab laser ntaub ntawv tub sab tub nyiag systems. Cov tshuab ua hauj lwm los ntawm kev tsim kom muaj ib tug hais lus masking spectrum filterable los ntawm broadband acoustic suab nrov nyob rau hauv dim pa, cua sov, dej, raws li zoo raws li nyob rau hauv lub tsev hnab ntawv.

Cov ntaub ntawv tiv thaiv cov khoom: xov tooj

Xov kab yog xav tau lub feem ntau tej zaum txoj kev ntawm cov ntaub ntawv to. Feem ntau cov pab kiag li lawm rau lub active kev tiv thaiv ntawm tus xov tooj kab los neutralize thiab mloog nyob rau ib cov ntaubntawv povthawj khoom uas yog kev cob cog rua ntawm qhov chaw nres tsheb thiab lub UE. Kev pab tiv thaiv yog siv los ntawm generating ib tug xov tooj kab siab thiab tsawg zaus cuam, kho cov hluav taws xob tam sim no noj nyob rau hauv txoj kab thaum lub sij hawm ib tug hu, ua yuav txo tau ntawm qhov zoo tshaj rau cov tswv yim teeb liab eavesdropping khoom siv, thiab blocks acoustic pib cov ntaubntawv povthawj siv apparatus. Yog hais tias lub xov tooj cua transmitters siv, ces muaj kuj yog ib tug channel los yog zaus ua haujlwm plooj kis tau tus mob spectrum.

Kev txhais tau tias ntawm cov ntaub ntawv tiv thaiv: Hauv Systems

Niaj hnub nimno ua lag ua luam yog tsis tau nyob ua ib ke tsis muaj kev siv ntawm loj tagnrho ntawm cov ntaub ntawv, uas siv hluav taws xob khiav tshuab, uas tsim loj leeb electromagnetic tawg. Nrog kev pab los ntawm tshwj xeeb kev txhais tau tias kev cuam tshuam lawv kuj muaj nyob sab nraum lub tshuaj cheeb tsam, thiab ces tag nrho rov qab kho cov ntaub ntawv. Nyob rau hauv tas li ntawd mus rau tej radiations uas twb muaj lawm nyob ze hluav taws xob yeej ib txwm muaj cov lus qhia quasistatic hluav taws xob thiab sib nqus teb uas sai dua li qub nrog deb, txawm li cas los, yuav tsum tau txoj kev taw qhia chains uas nyob ze txaus. Tej liaj teb yog tseem ceeb ntawm frequencies ntawm kaum tawm kilobytes rau kaum ntawm megahertz. Nyob rau hauv cov ntaub ntawv no, nws yuav tau mus cuam tshuam thaum kev cob cog rua ncaj qha mus rau cov kev sib txuas lus tau txais apparatus sab nraum lub tiv thaiv cheeb tsam. Yuav kom tshem tawm cov to ntawm cov ntaub ntawv los ntawm tej raws thov suab nrov generators, uas yog muab kev koom tes nyob rau hauv ua ib tug active masking spurious electromagnetic tawg.

Raws li koj tau pom, thaum lub caij muaj txoj kev thiab txhais tau tias ntawm cov ntaub ntawv tiv thaiv, uas yuav siv tau nyob rau hauv hnub no lub tuam txhab uas muag.
