Yintoni ijenereyitha yamaza okanye ijenereyitha yomqondiso?

ijenereyitha yamaza, ijenereyitha yomqondiso

Un ijenereyitha yamaza, okanye ijenereyitha yomqondiso, Sisixhobo esisetyenziswa ikakhulu kwimimandla yemizi-mveliso evelisa umqondiso wombane ngendlela yamaza onokungeniswa kwisekethe ye-elektroniki ukuze kuqhutywe iintlobo ngeentlobo zeemvavanyo kunye nolunye uvavanyo lweshishini kunye nezixhobo zokulinganisa. Oko kukuthi, ngelixa iimpawu ezivela kwisekethe zilinganiswa kwi-oscilloscope, kwijeneretha zifakwe kwisekethe ...

Ijeneretha yomqondiso inokuvelisa iifomati eziphindaphindayo nge iimilo eziqhelekileyo ezifana nesikwere, i-pulse, sinusoidal, triangular, sawtooth, phakathi kwezinye. Enesicelo kwiinkalo ezininzi, kungekuphela nje i-elektroniki, kodwa nakwizicelo zombane.

Kubalulekile ukuba uqaphele ukuba i-generator wave Ayinamsebenzi wokulinganisa umqondiso oyivelisayo, nangona ungayibonisa. Umsebenzi wayo oyintloko kukunika amandla okanye ukuvavanya iisekethe zombane okanye ii-activators kwiindawo zoshishino, okanye iilebhu zombane, zombini ekuphuhliseni nasekuqinisekiseni ukusebenza kwazo.

Njengoko benditshilo ngaphambili, iijeneretha zamaza zisetyenziselwa velisa imiqondiso ngamaxesha, apho i-voltage ihluka ngezikhathi ezithile ngexesha, ivumela ixesha layo (ixesha le-oscillation epheleleyo) kunye ne-amplitude yayo (ixabiso eliphezulu lombane wesignali) ukuba ilawulwe. Nangona kunjalo, inokudlala indima ebalulekileyo ekuveliseni amaza angengawo awexesha.

Isetyenziswa ikakhulu kwi uyilo, uvavanyo kunye nokulungiswa zezixhobo zombane. Ukongeza, inokuba nezicelo zobugcisa kwaye isetyenziswe kwicandelo lezonyango. Kule mihla, ngenxa yenkqubela phambili yetekhnoloji, kukho iijenereyitha zemiqondiso ekhethekileyo yemisebenzi eyahlukeneyo. Ezi zixhobo zinokudityaniswa ngokuthe ngqo kwiikhomputha kwaye zinikeze imisebenzi efana nokungena kweempawu ezenziweyo kunye nokukwazi ukucwangcisa i-generator ukuvelisa ulandelelwano oluthile lweempawu.
