Men ushbu labarato’riyani bajarish paytida BT da yasalgan UB kuchaytirgich sxemasini tadqiq etish mavzusida ish olib borib, bipolyar tranzistorlar haqida ma’lumotlarga ega bo’ldim. Va uning ulanish sxemalarini ulab natija oldim va ilingan natijalarni grafiklar yotdamida tasvirladim va ularni bir biri bilan solishtirdim.
