4.3. Построение автоматной таблицы выходов блока б3
d
Рисунок 8. Входные и выходные сигналы блока Б3
Для проектирования автоматной таблицы на основании словесной формулировки составим первоначальную таблицу истинности, в которой указывается последовательность поступления входных сигналов и отражается связь между входными и выходными сигналами. Столбцы таблицы истинности соответствуют входным и выходным сигналам устройства управления, строки - входным набором. Каждому входному набору ставится в соответствие определённое значение сигналов.
