11-Mavzu:Stchorchik regisrtlar
Reja :
1)Schotchik registrlar haida
2)O’nli schotchiklar
3) Reversiv schyotchiklar
Kirish yo’li impulslarini sanashga mo’ljallangan E'HM uzeli schyotchik deb ataladi.
Ularni sanoq sistemasi asosiga, qanday maqsadda ishlatilishiga, sanash amalini tashkil qilish
usuliga, honalararo bog’lanishni qurish usuliga hamda ularni qurishda ishlatiladigan
e'lementlar turiga qarab farklash mumkin.
Sanoq sistemchsi asosi bo’yicha schyotchiklar ikkili sanoq sistemasida ishlovchi
schyotchiklarga (sanash moduli 2
P
ga teng, bu erda p - schyotchik honalari soni) va ihtiyoriy
asosli (sanash moduli yoki sanash koe'ffisienti K
cr
ikkining darazhasiga karrali bo’lmagan)
schyotchiklarga bo’linadi.Qanday maqsadda ishlatilishiga qarab jamlovchi, ayiruvchi va
reversiv schyotchiklarga ajratiladi.Sanash amalini tashkil qilish bo’yicha sinhron va asinhron
schyotchiklar bo’ladi. Honalararo bog’lanishni qurish usuliga qarab ketma-ket, boshdan-
oyoq parallel va gruppali ko’chirishli schyotchiklarni farqlash mumkin.
Schyotchiklarda asosan triggerlar ishlatilsa-da, ularni mantiqiy e'lementlari yordamida ham
qurish mumkin. Bunday schyotchiklar kombinacion schyotchiklar nomini olgan.
