Lub lim suab yog qhov nyob ntawm qhov zaus Amplifier Circuit Court, ua hauj lwm nyob rau hauv lub suab ntau zaus, 0 Hz mus tshaj 20 kHz.
Ntau hom lim muaj nyob rau hauv daim ntawv thov suav nrog cov duab sib npaug, cov synthesizers, suab teebmeem, CD player thiab virtual reality systems.
Ua ib lub suab nrov zaus, hauv nws daim ntawv yooj yim tshaj plaws, lub suab lim tau tsim los ua kom nrov, dhau los lossis ua kom tsis zoo (tsis zoo amplification) qee qhov ntau zaus.
Cov hom muaj xws li cov lim dej qis, uas dhau los ntawm cov zaus hauv qab lawv cov zaus txiav tawm, thiab ua kom cov zaus qis dua qhov kev txiav tawm ntau zaus.
Lub tshuab lim high-pass ua qhov sib txawv, dhau qhov zaus siab tshaj qhov kev txiav tawm zaus, thiab ua kom cov zaus qis dua qis dua qhov txiav tawm zaus.
Lub lim bandpass hla ntau zaus ntawm nws ob qhov kev txiav tawm zaus, thaum txo qis cov neeg sab nraud.
Ib lub lim dej tsis lees paub, txo qis zaus ntawm nws ob qhov kev txiav tawm zaus, thaum dhau cov neeg sab nraud 'tsis lees paub' ntau yam.
Ib qho kev lim dej tag nrho, dhau txhua zaus, tab sis cuam tshuam rau theem ntawm cov khoom siv sinusoidal raws li nws cov zaus.
Hauv qee qhov kev siv, xws li hauv kev tsim cov duab vaj huam sib luag lossis CD player, cov ntxaij lim dej yog tsim los ntawm cov txheej txheem ntawm lub hom phiaj xws li hla band, hla band attenuation, nres band, thiab nres band attenuation, qhov twg cov hlais bands. zaus ntau npaum li cas lub suab yog attenuated tsawg tshaj li qhov siab tshaj plaws, thiab nres bands yog cov zaus ntau zaus uas lub suab yuav tsum tau attenuated los ntawm qhov tsawg kawg nkaus.
Hauv cov xwm txheej nyuaj dua, lub suab lim tuaj yeem muab lub voj voog tawm tswv yim, uas qhia txog resonance (ringing) nrog rau attenuation.
Cov lim suab kuj tuaj yeem tsim los muab nce (boost) thiab attenuation. Hauv lwm cov ntawv thov, xws li nrog cov khoom siv hluav taws xob lossis cov teebmeem suab, qhov zoo nkauj ntawm cov lim yuav tsum raug ntsuas raws li kev xav.
Cov lim suab tuaj yeem siv tau rau hauv analog circuitry raws li cov ntxaij lim dej analog lossis hauv DSP code lossis khoos phis tawj software ua cov ntxaij lim dej digital.
Feem ntau, lo lus 'suab lim' tuaj yeem siv los txhais tau tias txhua yam uas hloov cov ntoo, lossis cov ntsiab lus sib haum xeeb ntawm ib qho suab teeb liab.
Kuv yog Joost Nusselder, tus tsim ntawm Neaera thiab tus neeg lag luam cov ntsiab lus, txiv, thiab nyiam sim cov cuab yeej tshiab nrog guitar ntawm lub siab ntawm kuv txoj kev mob siab rau, thiab ua ke nrog kuv pab neeg, Kuv tau tsim cov ntsiab lus ntawm blog txij li xyoo 2020. los pab cov neeg nyeem siab ncaj nrog cov ntaub ntawv kaw lus thiab cov lus qhia guitar.
