Hauv electronics, nce yog ib qho kev ntsuas ntawm lub peev xwm ntawm ob-chaw nres nkoj Circuit Court (feem ntau ib amplifier ) kom muaj zog los yog amplitude ntawm lub teeb liab los ntawm lub tswv yim mus rau qhov chaw nres nkoj tso zis los ntawm kev hloov lub zog los ntawm qee lub zog rau lub teeb liab. Nws feem ntau qhia siv lub logarithmic decibel (dB) units ("dB nce ").
Ib yam li ntawd, tib neeg nug, ua li cas koj suav qhov nce ntawm lub amplifier?
Amplifier nce tsuas yog qhov piv ntawm cov zis faib-los ntawm cov tswv yim. Tau txais tsis muaj units raws li nws qhov piv, butin Electronics nws feem ntau muab lub cim "A", rau Amplification . Ces tus nce ntawm ib amplifier yog yooj yim xam raws li "tso zis teeb liab faib los ntawm lub teeb liab input".
Kuj Paub, dab tsi yog qhov nce ntawm lub subwoofer? Cov nce tswj lub suab hauv tsev subwoofer tso cai rau peb calibrate cov bass qib uas tsim los ntawm cov subwoofer kom phim cov zis los ntawm cov neeg hais lus hauv qhov system. A nce tswj kho qhov tso zis ntau ntau * txheeb ze * rau cov tswv yim qib. Qhov ntawd yog ib qho kev sib txawv tseem ceeb.
Ib yam li ntawd, tib neeg nug, qhov nce hauv suab yog dab tsi?
Ob leeg nce thiab theem hais txog lub suab nrov ntawm lub suab . Txawm li cas los xij, nce yog theem input ntawm lub clipsand ntim yog cov zis. Hauv kev kaw cia suab , nce yog thawj qhov kev tswj hwm uas lub teeb liab microphone mus dhau hauv amixer thaum qib raug kho tom qab ntawd.
Dab tsi yog lub luag haujlwm ntawm amplifier?
Ib amplifier yog ib qho khoom siv hluav taws xob uas ua rau qhov voltage, tam sim no, lossis lub zog ntawm lub teeb liab. Amplifiers yog siv hauv kev sib txuas lus wireless thiab tshaj tawm, thiab hauv cov khoom siv suab ntawm txhua yam. Lawv tuaj yeem muab faib ua cov cim tsis muaj zog amplifiers los yog lub zog amplifiers.

Dab tsi yog qhov sib txawv ntawm lub thawv thiab lub thawv ntawv thiab lub thawv ntawv yog dab tsi?
Ib lub thawv thiab cov ntawv nplawm (qee zaum hu ua boxplot) yog ib daim duab uas nthuav tawm cov ntaub ntawv los ntawm tsib lub ntsiab lus. Nyob rau hauv ib lub thawv thiab whisker zajlus: qhov kawg ntawm lub thawv yog lub sab sauv thiab sab quartiles, yog li lub thawv spans lub interquartile ntau yam. qhov nruab nrab yog cim los ntawm ib txoj kab ntsug hauv lub thawv
Dab tsi yog qhov qub txeeg qub teg Dab tsi yog qhov sib txawv ntawm qhov qub txeeg qub teg piav nrog piv txwv?
Inheritance yog ib txoj hauv kev kom tau txais cov yam ntxwv thiab kev coj cwj pwm ntawm ib chav kawm los ntawm lwm chav kawm. Cov chav kawm uas cov tswv cuab tau txais qub txeeg qub teg yog hu ua chav kawm hauv paus, thiab chav kawm uas tau txais cov tswv cuab tam sim no hu ua chav derived. Inheritance siv IS-A kev sib raug zoo
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
Dab tsi yog qhov txawv ntawm nce kauv thiab nqes kauv router me ntsis?
Peb qhov yooj yim cutter configurations rau kauv khoom yog up-cut, down-cut, thiab ib tug ua ke ntawm ob, hu ua compression me ntsis. Ib tug down-txiav me ntsis xa cov chips downward; ib tug txiav me me xa lawv mus rau pem hauv ntej shank. (Nyob ntawm lub rooj router, tag nrho cov kev taw qhia yog thim rov qab.)
