Tsawg zaus thiab zoo li

Ntses bass thaj tsam - tswvyim nrog rau ib tug ntau yam ntawm lub suab audible rau tib neeg pob ntseg. Nyob rau nruab nrab nws yog nyob rau hauv ntau ntawm 20 Hz mus rau 20 kHz. Audiogram, uas txiav txim seb lub peev xwm paub tau tus qis pib ntawm txhua zaus, muaj lawv tus kheej ib tug neeg tus yam ntxwv, yog li peb yuav tham txog nruab nrab statistical lub rooj sib hais. Feem ntau, cov frequencies hauv qab no 40 Hz thiab saum toj no 16 kilohertz es feem xyuam rau txoj rau lub suab xim tshaj qhov muaj nws tus kheej.

Cov kab kev los ntawm me nyuam thiab kis cov khoom sib txawv, li ntawd, sib txawv thiab cov kev cai rau nws. Piv txwv li, cov xov tooj reproduces suab zaus ntawm los ntawm 200 Hz mus rau 3 kHz, thiab qhov no yog txaus rau kom meej meej lauj tag nrho cov lus ntawm lub raj lwm kawg los yog, nyob rau hauv cov ntaub ntawv ntawm kev siv lub mobile apparatus nyob rau hauv lub microphone. Tib yam siv rau thiaj li hu ua "neeb" - Translational tham. Txawm li cas los, nyob rau hauv kev sib hwm ntawm cov zaus band dhau lub ntiaj teb no tus qauv, raws li uas cov khoom hauv chav kawm ntawv Hi-Fi yuav tsum tau muaj ib zaus band ntawm 20 mus rau 20000 Hz thiab dav.

ib tug tsawg zaus amplifier siv lug raws li ib feem ntawm hluav taws xob circuits ntawm ntau yam muaj thiab domestic pab kiag li lawm, raws li ib tug nyias muaj nyias ib lub xov tooj cua. Lawv yog cov nyob rau hauv computers, TV, xov tooj cua, CD-neeg uas ua ntawv, ratsiyah, mobile xov tooj, hu rau qhov chaw nres tsheb thiab ntau lwm tus neeg paub yam rau peb uas.

Lub ntsiab yam ntxwv ntawm cov amplifier yog raws li nram no:

- Rau cov zis muaj hwj chim. Niaj hnub no nws yog suav tias yog txawv. Piv txwv li, nyob rau hauv thiaj li yuav tsim nyob rau hauv maloponimayuschego tib neeg notions ntawm kub ntim, uas nws yuav tsum tau txaus siab rau, nyob rau hauv pob nrog lub receiver los yog amplifier, koj yuav saib tau ib tug kiag li monstrous plaub tug lej xov tooj cim «PMPO». Cov ntawv no yuav tsum nyob rau hauv tus txhais hais tias lub ncov load, uas muaj peev xwm muab ib tug luv luv lub suab khoom. Qhov tiag hwj chim - yog muaj nuj nqis uas saib kuas undistorted sine yoj daim ntawv ntawm ib zaus ntawm 1,000 Hz yog cov tswv yim mus rau lub amplifier.

- Distortion - tus nqi uas qhia ntau npaum li cas cov uas tsis muaj frequencies nyob rau hauv lawv daim ntawv no mus rau lub tso zis theem txawv los ntawm lub tswv yim teeb liab. Qhov no yog tej zaum qhov tseem ceeb tshaj plaws parameter, sib tham txog yuav ua li cas zoo ua thiab Mekas tsawg zaus amplifier.

- Dynamic khwv. Qhov no yam ntxwv tseem ceeb heev rau high-amplifying khoom, nws muab ib lub tswv yim ntawm yuav ua li cas straightforward teeb nce. Nyob rau hauv lwm yam lus, ib tug txaus wide dynamic ntau yam yuav tau undistorted tag nrho cov tsawg zaus, tsis hais ntawm lawv theem. Thiab heev nyob ntsiag to, thiab ib tug heev nrov nrov suab yuav tsum tau ua si nti. Qhov no zoo yog cov yam ntxwv ntawm lub raj amps.

- Zaus teb. Nyob rau nws tau hais nyob rau hauv tsab xov xwm, koj yuav tsuas ntxiv ib feature nws ua niaj hnub. Qhov tseeb tiag mas, nws yog ib tug ncaj kab uas tig mus rau lub abscissa scale nrog zaus thoob plaws hauv lub operating ntau yam.

Cov tsis txhais los ntawm lub zoo uas cov uas tsis muaj frequencies yog dua classical amplification cov khoom. Nyob rau hauv ib co niaj hnub khoom vaj khoom tsev suab paj nruas kuaj zaus yam ntxwv yog txhob txwm tshaj tawm distorted los tsim zam los xws li ntses bass thaj tsam li Cheebtsam lossis ultrahigh zaus, uas muaj ib tug nyhuv dejnum rau lub rooj sib hais thiab lub hlwb.
