Lub suab amplifier yog dab tsi?
Lub suab amplifiersyog cov khoom siv lossis cov khoom siv hluav taws xob uas ua kom nrov thiab tsis muaj suab nrov kom tsav lub impedance qis, inductive hais lus load.Lawv yog siv nyob rau hauv daim ntawv thov xws li high-powered suab systems nyob rau hauvtsheb thiabtsev, TV teeb, lub mloog pob ntseg thiabmicrophones.Qee cov khoom siv suav nrog cov serial interface rau kev tswj hwm ntawm cov tsis tau los ntawm lub processor.Lawv kuj muaj nyob rau hauv ntau hom teeb liab input, suav nrog analog, pulse width modulation (PWM) thiab ntau cov qauv kev lag luam digital.Piv txwv ntawm cov qauv digital feem ntau txhawb nqa yog: I2S, lub sij hawm faib multiplex (TDM), sab laug-justified (LJ) thiab txoj cai-justified (RJ).
Lub suab amplifier muaj ntau tus yam ntxwv los xav txog.Amplifiers nrog cov khoom siv digital yuav txhawb nqa 'tus nqi piv txwv' uas tuaj yeem nyob ntawm 8 kHz txog 192 kHz.Tej zaum lawv yuav raug tsim los koom nrog cov suab digital ntws los ntawm DSP thiab muaj cov kev teeb tsa zoo rauBluetooth hais lus,suab bars, chaw nres tsheb dockingthiab txawmsub woofers.Analog inputs tej zaum yuav ib leeg-kawg los yog txawv thiab muaj xws li ib tug preamp, clip detection thiab tweeter ntes.Lub hwj chim amplifiers tej zaum yuav raug kaw los yog qhib lub voj tsim, suav nrog kev tawm tswv yim sab hauv thiab kev txwv tam sim no.Qee lub amplifiers yuav muaj qhov txhaum, dhau qhov ntsuas kub thiab ntsuas qhov clipping, thiab tej zaum yuav muaj raws li cov ntawv tso tawm digital rau lub processor txuas.Feem ntau lub suab amplifiers yuav suav nrog MUTECircuit Court.
Ntau lub suab amplifiers yuav txhawb nqa ntau cov channel.Cov no feem ntau muaj lub zog tso zis rau kev ua haujlwm txuas ntxiv mus rau hauv tus neeg hais lus impedance (piv txwv li 4 Ohms).Lawv kuj tseem yuav raug ntsuas rau qhov tshwj xeeb tshaj plaws tag nrho kev sib haum xeeb thiab lub suab nrov (THD + N) nyob rau hauv qhov sib txawv load thiab lub zog.Power Supply Rejection Ratio (PSRR) kuj yog ib qho tseem ceeb heev rau kev txiav txim siab ntawm cov hum thiab suab nrov ua ke los ntawm cov khoom siv hluav taws xob.Ntau Channel Suab Amplifiers tuaj yeem txhawb nqa "choj khi load" kev teeb tsa uas cov khoom siv sib xyaw ua ke los tsav ib qho kev thauj khoom thiab ua kom cov zis tawm.Qhov no yog qhov tseem ceeb hauv sub-woofer amplifier tsim.
Class D power amplifier yog dab tsi?
Class D fais fab amplifier yog ib hom hluav taws xob amplifier, tseem hu ua fais fab hloov amplifier.
Qhov zoo ntawm Class D fais fab amplifiers:
1, Kev ua haujlwm siab: Class D lub zog amplifier tuaj yeem muab kev siv hluav taws xob tsawg, kev ua haujlwm zoo, lub teeb yuag.Qhov no yog ib qho teeb meem tseem ceeb rau portable amplifiers thiab bass amplifiers.
2, daim ntawv thov dav: Class D lub zog amplifier muaj ntau yam kev siv.
3, lub suab meej: D cov nyhuv hauv chav kawm tuaj yeem hloov kho tus txheeb ze zaus, lub suab meej, qhov tseeb ntawm lub suab thiab duab.
4, tuaj yeem ua tau ntau lawm: D chav kawm fais fab amplifier tsuav yog qhov chaw nyob ntawm qhov chaw raug muab tso rau, tuaj yeem ua ntau lawm, muaj kev nyab xeeb thiab txhim khu kev qha.
5, multifunctional: D chav kawm fais fab amplifier tuaj yeem ncaj qha rau kev tswj chaw taws teeb, saib xyuas thiab lwm yam haujlwm, tsis muaj lwm yam khoom siv.
6. Kev txuag hluav taws xob: Piv nrog AB amplifiers, Class D fais fab amplifiers xav tau cov dab dej kub me me thiab cov khoom siv hluav taws xob.
