MAVZU: Triggerlar ishini tadqiq qilish


1. Ishni bajarishdan maksad .
Axborotni potentsiallar usuli bilan kursatadigan VA-INKORva VA-YoKI–INKOR mantikiy bazislarda asosiy trigger kurilmalari strukturalarini tekshirish va tadkik etish .
2. Ishni bajarish rejasi .
1. Statik rejimda trigger xolatini nazorat kilish .
2. Dinamik rejimda trigger xolatini nazorat kilish .
3. RS - triggerning sxemasini yigish.
4. D- triggerning sxemasini yigish.
5. JK- triggerning sxemasini yigish.
6. T -triggerning sxemasini yigish .
3. Ishni bajarish tartibi .
1.Statik rejimda ishlayotganda trgger xolatini nazorat kilish uchun uning kiymatini chikishlariga indikator lampochkalarini ulang lamopochkaning yonib turgan xolati logik “1” bildiradi .
Triggerni ishga tushirish uchun R va S kirishlarga tubmlerlarini , S kirishga esa musbat kutbli impuls signallarini ulang.D va JK iggerlarni tekshirayotganda D, JK kirishlarga tublerdan , C kirishga esa musbat kutbli yakka impuls signallarini ulang .
2. Dinamik rejimda ishlash uchun R va S kirishlarga tumblerlardan signallar bering. Ostsillogrammani chikishlardan oling. Ostsillografni sinxronlash Q chikishdagi signallar orkali amalga oshiriladi.
3. VA-INKOR elementi asosida RS-asinxron triggerni yiging. Uni statik rejimda tekshiring, utish jadvalini tuzing . (1-rasm )

4. 
   VA-INKOR elementi asosida sinxron RS –triggerni yiging.Uni statik rejimda tekshiring .Utish jadvalini tuzing. (2-rasm )
   

5. Sinxron D- tiggerni sxemasini yining .Uni statik rejimda tekshiring va utish jadvalini tuzing.(3-rasm )
6. VA-INKOR elementi asosida JK –triggerni yiging .Uni statik va dinamik rejimlarda tekshiring .Utish jadvalini tuzing va ostsillogrammani chizing. (4-rasm )
7. Integral tiggerlarni statik va dinamik rejimlarda tekshiring .JK va D –triggerlar uchun utish jadvalini tuzing va ostsillogrammani oling .
8. JK trggerlari asosida T- trbggerlarini sxemasini yiging .Uni statik va dinamik rejimda tekshiring. (5-rasm )
