Yuav ua li cas yog ib lub hwj chim amplifier thiab dab tsi yog nws rau?

Lub hwj chim amplifier - ib tug tshwj xeeb hluav taws xob ntaus ntawv tsim los hloov ib tug me me rau ntawm lub hwj chim ntawm lub fais teeb liab uas yog nkag los ntawm ib qhov chaw mus rau hauv ib tug ntau haib teeb liab. Tom qab tag nrho, los tswj lub electro-pab kiag li lawm, transducers, xws li headphones los yog hais lus, koj xav tau ib tug haib thawj lub teeb liab tsis muaj distortion, thiab qhov chaw yog feem ntau tsis tau muab cov kev kawm lub teeb liab lub hwj chim, los sis pauv nws undesirable los.

Lub hwj chim amplifier tej zaum yuav ib daim ywj siab unit nrog nws tus kheej tswj vaj huam sib luag thiab cov system thiab roos ib puab tug tswv cuab ntawm lub ntaus ntawv thiab yuav tsum tau soldered mus rau lub hybrid Circuit Court. Qhov no ntaus ntawv yog qhov tseeb link nyob rau hauv tej amplification Circuit Court.

Lub hwj chim amplifier peev xwm yuav txawv los ntawm nws cov kev siv. Feem ntau muaj ob lub ntsiab qhov chaw ntawm qhov kev siv: lub tsev thiab kev. Koj muaj peev xwm kuj tau faib rau lawv raws li cov schemes khiav rau ib leeg-twb thiab thawb-pull hwj chim amplifier. Ib leeg-cycle ua hauj lwm nyob rau hauv lub thiaj li hu ua linear nce hom. Nyob rau hauv no hom, cov tam sim no ntws los ntawm cov transistor thaum lub sij hawm tag nrho lub sij hawm.

Lub hwj chim amplifier yog nyob rau hauv kiag li tej dais los yog apparatus uas reproduces suab Pib ntsais koj teeb ntawm ib sab zaus spectrum. Txij li thaum thawj lub teeb liab uas yog nyeem chiv yog feem ntau heev me me hwj chim los mus xa nws mus rau lwm pab kiag li lawm thiab nws yog tsim nyog los siv amplifiers. Xws li yuav ua tau nyob rau hauv tej lub xov tooj txawb, daim kab xev recorders, computers thiab laptops, thiab txawm yog me nyuam cov khoom ua si uas yuav tham (uas muaj hais lus). Nyob rau hauv xws cuab yeej siv thiab tsev neeg siv amplifiers. Lub hom phiaj ntawm xws li - amplification ntawm qhov hluav taws xob lub teeb liab mus rau lub audible ntau yam ntawm qhov tseem ceeb uas muaj peev xwm tau txais qhov nruab nrab tib neeg pob ntseg neeg nyob li (feem ntau los ntawm 15 mus rau 22 kHz). Nws yuav tsum tau muab sau tseg tias muaj hnub nyoog ntau yog significantly txo (mas dauv nws sab sauv txwv), lub rooj sib hais yuav tsis rhiab - thiab cov neeg feem coob nyob rau hauv lub hnub nyoog no tsis tau perceive suab ntawm ib zaus ntawm ntau tshaj 16-17 kHz.

Nyob rau hauv lub lag luam yog ntau kev amplifiers, piv txwv li, xws li ib tug ntaus ntawv raws li ib tug Translational hwj chim amplifier. Nws yog siv los chime nyob rau hauv chaw ua hauj lwm vaj tse, muaj vaj tse thiab loj qhib qhov chaw, stadiums thiab malls. Lawv lub hom phiaj - kom nrov loj thiab kis ib tug lub teeb liab rau broadcasting lub koom haum (tshaj tawm hauv xov lub teeb liab) rau ib tug ntau yam ntawm loj yam khoom.

Zoo li xws li ib tug ntaus ntawv raws li ib lub hwj chim amplifier, tej zaum yuav yog tus tseem raznobraznye thiab sib txawv heev nyob rau hauv daim ntawv thov thiab lub hom phiaj. Tej zaum kuj yuav sib txawv nyob rau hauv cov kev teeb tsa. Piv txwv li, lub suab hwj chim amplifier muaj ib tug tshwj xeeb system rau me nyuam, kev tiv thaiv los ntawm dej thiab dej, tas mus li cua system. Tag nrho cov no ntau npaum li cas kom ib tug ntev npaum li cas lub sij hawm kev lag luam ntawm lub suab qhov cuab lub zog cov khoom nyob rau hauv tej yam kev mob ntawm ntau load.
