Qhov kev txiav txim siab ntawm qhov hnyav faib nkhaus ntawm lub tshuab tsis siv neeg qhov hnyav (qhov hnyav nrhiav tau ntau) yog nyob ntawm kev hloov kho ntawm cov khoom siv hnyav (lub hom phiaj hnyav) thiab qhov hnyav siv ntawm lub ntim ze tshaj qhov hnyav. Txawm hais tias tej zaum yuav muaj qee qhov ntim nrog qhov siab lossis qhov hnyav, thaum muaj ntau lub ntim, qhov feem ntawm cov ntim yuav maj mam txo, uas yog ib qho kev faib tawm uas hu ua "ib txwm faib" lossis Gaussian faib. Hauv kev faib tawm ib txwm muaj, ob lub ntsiab lus no yog qhov tseem ceeb tshaj plaws nkhaus ntawm txoj hauj lwm thiab qhov dav.
Ntsuam xyuas cov kab ntau lawm ntawm cov khoom, nkag mus rau hauv lub tshuab hnyav tsis siv neeg, thiab thauj cov kev ntsuas los ntawm kev nrawm (sab nrawm); Tshawb xyuas qhov hnyav ntawm cov khoom (thaum lub sijhawm txav ntawm qhov hnyav, lub sensor yuav deform nyob rau hauv qhov kev txiav txim ntawm lub ntiajteb txawj nqus, txhawb kev hloov ntawm nws impedance, ib qho analog tso zis teeb liab; lub amplifier circuit output ntawm lub luj module ADC
Thiab sai sai hloov nws mus rau hauv lub teeb liab digital, xam qhov hnyav los ntawm lub cev nyhav symmetrical module processor; Lub teeb liab hnyav ntawm qhov hnyav module processor yog amplified, ua tiav, thiab ntsuas. Yog tias qhov hnyav ntawm cov khoom ntau tshaj li qhov teev saum toj thiab qis qis, cov lus qhia processor yuav tsis lees paub cov khoom tsis tsim nyog.
