Msindo Operational: inkcazo, umgaqo yokusebenza, ukusetyenziswa

elektroniki Analog - enye macandelo ezibalulekileyo bombane, elisuke laba ilitye sandise ukuya evela resistors, rheostats kunye ammeters ukuba 'umlinganiselo' digital. Ukusebenzisa yindibaniselwano yeekhomponenti zombane ezininzi nokwakha i iziphaluka ezintsonkothileyo, elektroniki analog uvumele ukusetyenziswa kwazo ukufezekisa umzobo waloo sixhobo zilula-digital. Namhlanje, elektroniki analog - isiseko busebenze zombane esimbaxa namhlanje.

Enye elektroniki analog - op-amp, nto leyo icebo oluntsonkothileyo multistage usebenzisa semiconductors. Xa uhlobo elipheleleyo le lwento amagalelo amabini, ezo zocaphulo omnye komnye. Kuyaphawuleka ukuba enye yeempawu eguqulweyo ngokubaxwa i SIGILL uphawu abafumana node lixabiso enkulu inzuzo.

uphumezo elipheleleyo kuthetha ukuba lo mshini zokusebenza ibekwa ukugxininisa kwenye yokusebenza iibhloko nj. Busebenze zesi sixhobo, kwakunye nezinye zonke izinto, wafumana isiqu okhethekileyo. Njengoko umthetho, imizobo wokukhulisa yesekethe yokusebenza zimele unxantathu omkhulu. Kutshanje, Noko ke, kunokwenzeka ukufumana enye uphawu ngenxa ngombhobho - uxande unxantathu ngaphakathi. Kungenzeka, a ukwalatha Ndaziswa lula umzekeliso isixhobo kwi imizobo block.

Operational izicelo sesimangalo namhlanje zahlukahlukene kakhulu. Ezi zixhobo multistage ezisetyenziswa ezahlukahlukeneyo yokukhulisa ukuba kwizalathisi ezahlukeneyo. Ngaphezu koko, lo msindo yokusebenza isoloko isetyenziswa ngendlela Umvelisi iimpawu zombane, kwakunye izihluzi ngenxa odiyo uluhlu frequency. Ukongeza, amandla iye sisixhobo sele kwinkqubo yolawulo kwisazobe kukho ezininzi eziphathekayo (umzekelo, izitishi yemozulu).

Umgaqo esebenza ngayo lo mshini zokusebenza idla kuthelekiswa amaxolo avumba limnandi, inaliti yayo baphambuke ngendlela apho umthwalo indebe inkulu. Kuphela msindo zokusebenza kuyimfuneko ukuba uqaphele enye neendebe yi "+", okwesibini - "-" kunye nexabiso elilinganisiweyo ukubuyisela volts endaweni grams. Ngoko ke, lo mshini yenza ombane imodyuli uthelekiso kwenye kunye igalelo yesibini. (- negative ngenye indlela) ukuba umahluko enokubakho kwi igalelo ngqo umkhulu kunothe uguqulo, le ombane HIV eveliswa imveliso.

Ukubuyela kule nokonyulwa yokukhulisa zokusebenza idayagram yesekethe kufuneka kuqatshelwe ukuba ufikelelo ngqo idla luchazwa ngegama "+" yaye inguqu - "-". Noko ke, abo abalinganiswa akuyi kusoloko kusetyenziswa! Ngamanye amaxesha amacebo e uphawu emnyango lingakulungele, kodwa endaweni zocaphulo ingqalelo igalelo ngendlela izangqa ezincinane.

Ukwenzela ukunciphisa uvakalelo lo msindo zokusebenza ukuya technical intlokoma igalelo uphawu yombane ungeneyo ngombhobho zokusebenza CCA - feedback negative. Ngokusetyenziswa kwamalungu beesekethe efana ukukhululwa compound kunye igalelo zocaphulo nge resistor ezinikeleyo, nokuphambuka kancinane ukusuka umqondiso ufako lwanikwa kwikhompyutha yi lo mshini ukusebenza ngexesha lokusebenza.

Ngamanye amaxesha kuba lo mshini yokusebenza isazobe yesekethe izixhobo ezinzima isebenzisa ingxelo eyakhayo, apho umchiza luvelise igalelo elihle kunye neziphumo kusetyenziswa resistor elizinikeleyo. isiphumo icala umdla ivela xa usebenzisa ingxelo eyakhayo - "loop hysteresis".

Elokuqukumbela, eli yokukhulisa zokusebenza zisetyenziswa unipolar nini, phi kwaye ugesi vuvabyi.
