Impendulo imvamisa amplifier - akukho ephelele

Impendulo imvamisa - igrafu mgudumbili ezibonisa indlela Ukuboshelwa iyakhula isibonakaliso ukuncika imvamisa yayo. Uma sikhuluma yokukhulisa umsindo imvamisa ongaphakeme, okungukuthi, imishini acoustic, impendulo imvamisa inquma engokwemvelo kanye yemvelo umsindo ukukhiqizwa kabusha.

ukuhlanekezela lomsindo kukhona komugqa futhi non-eqondile. Ukuze ufake phakathi ushintsho non-eqondile the umumo gagasi okukhipha, futhi eqondile - sithole flatness ngenkathi sigcina ezakheke ngayo.

Isici amplitude amplifier has isici: Ukuhlukaniswa abscissa, okuyinto sisetshenziswa ku ezahlukene amaza ezahlukene ezwakalayo has a lokulinganisa logarithmic - ayanda nobuningi, ezincane ngezikhawu phakathi iziqu. isibonisi ndlela walungisiswa angezwakali ezindlebeni zomuntu izici, okuyinto eyenza ukushintshashintsha kwezwi incipha njengoba ithoni.

An ekahle imvamisa impendulo lizofuna umugqa oqondile ovundlile. Kodwa njengoba wazi, ukuze alethe kuwe ngokuphelele ngokulinganayo futhi ngokulinganayo eveza yonke spectrum, ngisho ibanga kuqhathaniswa emincane ezwakalayo umsindo cishe kungenakwenzeka. Zonke ngalolu daba izici electronic izingxenye, wesifunda izingxenye (ezifana amplifier, Semiconductor noma tube, kanye nokwesekwa, capacitance futhi inductance). Noma yimuphi Transistor, wesifunda ehlangene, noma isibani nempendulo eyimfihlo. Kuphela Tuning ngokucophelela, umklamo okuhlongozwayo yonke idivayisi, ukuze sivale lapho sisilela non-ideality yezingxenye ngamunye. Lokhu kungase lekumele azuzwe nokukhetha izinto, kanye obujulile impendulo engeyinhle, okuyinto kunciphisa kokubili komugqa futhi ukuhlanekezela nonlinear.

Njengoba enhle imvamisa impendulo akukwazi, singakwazi kuphela khuluma ngezinto ngalo kuphambuka umugqa oqondele eksisi abscissa. Kuthathwa ngokuthi ushintsho lwenzuzo ngaphakathi kwama-decibel angu ezintathu ngeyokuzwa womuntu awuwona ezibucayi, Nokho ibhendi yokuvama lichazwa ngokuthi isikhawu phakathi empambana imigqa elele 3 dB ngezansi amagugu isiqongo inzuzo (ngokuvamisile esifundeni 1000 Hz) kusukela izici umugqa ezindaweni okuthiwa "ekupheleni amajika ". Akumele bazitshela ukuthi ukuvama "hhayi lidlule" ibanga lokuvama ngezansi nangaphezulu imingcele, bona ezwakalayo nje perceptibly sibi kakhulu.

Susa impendulo imvamisa amplifier kungenzeka esebenzisa Amadivayisi ezilula (oscilloscope futhi generator imisindo), noma ngokusebenzisa voltmeter ngqo. Ngenxa yalesi kubalulekile amadivayisi okokufaka isignali efanayo ezidlula, isibonelo, 200 mV, futhi amaza ezahlukene kanye ukukala amandla okukhiphayo, okubangela idatha kugrafu. On RADIOZAVOD ayiswe ulungise ukufana impendulo imvamisa nge ekhethekile zonke-wave generator, ukusuthisa lonke uhla okokufaka, kanye imitha, kubonisa umdwebo esikrinini. Endaweni ukukhiqizwa ngoba kuvela isheshe ukufeza imiphumela.

Izikhulumi, abasebenzi Inkokhelo ngoba amplifier, esikhundleni salokho, anezici zabo, futhi nabo sikude kakhulu nokuphelela. Ukuze bavale isikhala Imininingwane imvamisa impendulo izakhiwo amplifier zinikezwa amadivayisi njenge Izilawuli ithoni, noma multi-band equalizers. Ikilasi imishini ayinakho ezifana ukubeka Hi-End, imvamisa yayo impendulo kahle ngakho usethe futhi kuvunyelwane ngazo ngesipika ephelele ukuthi, ngaphezu ukusingatha ivolumu uguqule ukushintsha namanye amadivayisi ukulawula kuyadingeka.
