LABORATORIYA ISHI
Bajardi:Tursunaliyev Erkinjon
11- Laboratoriya ishi
Umumiy baza ulanish sxemasidagi bipolyar tranzistorningning statik Voltamper xarakteristikalarini tadqiq etish
Ishdan maqsad: Umumiy baza ulanish sxemasida bipolyar tranzistorlarning
asosiy statik xarakteristikalari va parametrlarini tadqiq etish. Laboratoriya ishini bajarish uchun topshiriq:
10.1. Laboratoriya ishini bajarish oldidan uing pasport ko‘rsatmalarini yozib oling.
10.2. Umumiy baza ulanish sxemasidagi bipolyar tranzistorning kirish va chiqish xarakteristikalar oilasini o‘lchashda 10.1-rasmda keltirilgan principal sxemani yig‘ing, sxemani o‘lchashda qo‘llaniladigan o‘lchov asboblari bilan tanishib chiqing
Umumiy baza ulanish sxemasidagi bipolyar tranzistorning kirish va chiqish xarakteristikalar oilasini o‘lchash sxemasi
10.1 – jadval. UB ulanish sxemasidagi BT ning kirish xarakteristikalari oilasi o‘lchash uchun
