Создать программный имитатор двоичной цифровой системы управления, имеющий следующую схему (см. Приложение 2):
1. Три логические устройства первого уровня:
Таблица. 1, N = 5.
2. Коммутация трех логических устройств первого уровня с входными X1, X2, X3 и инвертированными Y1, Y2, Y3 цепями:
Таблица. 2, N = 1.
3. Три логические устройства второго уровня:
Таблица. 1, N = 3.
4. Коммутация трех логических устройств второго уровня с тремя выходными цепями первого уровня:
Таблица. 3, N = 0.
Решение.
1. Таблица. 1, N = 5: OR1, AND1, OR2
2. Таблица. 2, N = 1: X2, X3; Y1, Y2; Y3, X1.
Входы OR1: X2, X3.
Входы AND1: Y1, Y2.
Входы OR2: Y3, X1.
3. Таблица. 1, N = 3: AND2, OR3, OR4.
4. Таблица. 3, N = 0: 1, 2; 3, 1; 2, 3.
Входы AND2: OR1, AND1.
Входы OR3: OR2, OR1.
Входы OR4: AND1, OR2.
Написание уравнений логической схемы программного имитатора начинается с выходов Z.
Z1=AND2=OR1*AND1=(X2+X3)*(Y1*Y2);
Z2=OR3=OR2+OR1=(Y3+X1)+(X2+X3);
Z3=OR4=AND1+OR2=(Y1*Y2)+(Y3+X1)
6. Исходный текст программы на языке Си.
