3.3. Синтез комбинационных схем, реализующих функции возбуждения элементов памяти управляющего автомата
Количество ЭП, составляющих память автомата, определяется по выражению
,где F – мощность множества А.
Для каждого TR (где
) по графу составляется каноническая таблица функций переходов и выходов, а на основе этих таблиц составляются функции возбуждения ЭП. Соответственно для T1, T2, T3, T4 это будут таблицы 16, 17, 18, 19.Таблица 16
