Sikuyenda mkuzamawu: kufotokoza mfundo ya ntchito, ntchito

Analogi zamagetsi - mmodzi wa chigawo chofunika kwambiri zamagetsi, umene wakhala mwala pakupita kusuntha kwa resistors, rheostats ndi ammeters kwa digito "muyeso". Ntchito osakaniza zigawo zambiri magetsi ndi kupanga madera zovuta, zamagetsi analogi walola ntchito zawo kukwaniritsa kujambula kwa losavuta zipangizo yadigito. Lero, analogi zamagetsi - maziko zovuta circuitry lero magetsi.

Mmodzi analogi zamagetsi - uthenga ulalikidwa-mkuzamawu, zomwe ndi zovuta multistage chiwembu ntchito semiconductors. Mu mawonekedwe tsinde la chida ichi ali zolowetsa awiri, amene kukalowa kwa wina ndi mzake. N'zochititsa chidwi kuti munthu wa makhalidwe osiyanitsidwa chizindikiro kulandira mfundo ndi phindu lalikulu la phindu lapansi.

Yofunika kuphedwa akusonyeza kuti mkuzamawu ntchito aikidwa kuti amakhazikika mu imodzi mwa ntchito Chip atilakwira. The circuitry pogwiritsa, komanso zinthu zina zonse, analandira mapangidwe apadera. Monga ulamuliro, ndi ntchito mkuzamawu dera zithunzi kuimira kansalu lalikulu. Komabe, posachedwapa nkotheka kupeza chizindikiro zina mkuzamawu ndi - ndi rectangle ndi kansalu mkati. Ambiri mwina, ngati chikhazikitso ndi polima wosalira fanizo la chipangizo mu zithunzi chipika.

Sikuyenda mkuzamawu ntchito lero yosiyanasiyana. zipangizozi multistage ntchito zosiyanasiyana amplifiers kwa zizindikiro zosiyana. Komanso, mkuzamawu ntchito kawirikawiri amagwiritsidwa ntchito jenereta ya chizindikiro magetsi, komanso Zosefera kwa zomvetsera pafupipafupi osiyanasiyana. Komanso, mphamvu wasanduka chida chofunika kwambiri pa dongosolo kulamulira chithunzi cha kuchuluka kwa zedi thupi (mwachitsanzo, maofesi nyengo).

Mfundo ntchito ya mkuzamawu ntchito kawirikawiri poyerekeza ndi mamba Apothecary, singano chimene anapanduka mu dera kumene katundu chikho waukulu. Only mkuzamawu ntchito m'pofunika kuona mmodzi wa makapu ndi "+", wachiwiri - "-" ndi mtengo mpandawo m'malo volts m'malo magalamu. Choncho, mkuzamawu umabala voteji poyerekeza gawo pa wina ndi athandizira chachiwiri. (- mwinamwake zoipa) ngati kusiyana ikhudzire athandizira mwachindunji ndi wamkulu kuposa osiyanitsidwa, ndi voteji zabwino ndi kwaiye pa linanena bungwe.

Kubwerera ku zoti amplifiers ntchito mu chithunzi dera tisaiwale kuti mwachindunji mwayi kawirikawiri amaimira "+" ndi osiyanitsidwa - "-". Komabe, ochitapo nthawi ntchito! Nthawi zina njira pakhomo chizindikiro sipakhala, koma m'malo kukalowa athandizira cholembedwa mu mawonekedwe a magulu ang'onoang'ono.

Pofuna kuchepetsa tilinazo wa mkuzamawu ntchito kwa luso Phokoso athandizira magetsi mbendera analowa mu ntchito mkuzamawu CCA - maganizo olakwika. Pogwiritsa ntchito zigawo dera monga kumasulidwa pawiri ndi athandizira kukalowa kudzera ndi resistor odzipereka, zolakwika pang'ono kuchokera anapatsidwa athandizira chizindikiro si anagwidwa ndi ntchito mkuzamawu pa ntchito.

Nthawi zina za ntchito mkuzamawu mu dera chithunzi cha zipangizo zovuta amagwiritsa maganizo abwino, kumene pawiri kuti pakhale gulu athandizira zabwino ndi linanena bungwe kudzera ndi resistor wodzipereka. ndi mbali zotsatira chidwi Umaoneka ntchito maganizo abwino - "hysteresis kuzungulira".

Pomaliza, ndi amplifiers ntchito ntchito ngati unipolar pamene, komwe ndi kotunga ochititsa kuti mphamvu.
