Построение полинома Жегалкина:
По таблице истинности функции E | A | D | Fж | 0 | 0 | 0 | 1 | 0 | 0 | 1 | 1 | 0 | 1 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | 0 | 0 | 1 | 1 | 0 | 1 | 1 | 1 | 1 | 0 | 1 | 1 | 1 | 1 | 0 |
Построим полином Жегалкина: F ж = C 000 ⊕ C 100∧E ⊕ C 010∧A ⊕ C 001∧D ⊕ C 110∧E∧A ⊕ C 101∧E∧D ⊕ C 011∧A∧D ⊕ C 111∧E∧A∧D Так как F ж(000) = 1, то С 000 = 1. Далее подставляем все остальные наборы в порядке возрастания числа единиц, подставляя вновь полученные значения в следующие формулы: F ж(100) = С 000 ⊕ С 100 = 1 => С 100 = 1 ⊕ 1 = 0 F ж(010) = С 000 ⊕ С 010 = 0 => С 010 = 1 ⊕ 0 = 1 F ж(001) = С 000 ⊕ С 001 = 1 => С 001 = 1 ⊕ 1 = 0 F ж(110) = С 000 ⊕ С 100 ⊕ С 010 ⊕ С 110 = 1 => С 110 = 1 ⊕ 0 ⊕ 1 ⊕ 1 = 1 F ж(101) = С 000 ⊕ С 100 ⊕ С 001 ⊕ С 101 = 1 => С 101 = 1 ⊕ 0 ⊕ 0 ⊕ 1 = 0 F ж(011) = С 000 ⊕ С 010 ⊕ С 001 ⊕ С 011 = 1 => С 011 = 1 ⊕ 1 ⊕ 0 ⊕ 1 = 1 F ж(111) = С 000 ⊕ С 100 ⊕ С 010 ⊕ С 001 ⊕ С 110 ⊕ С 101 ⊕ С 011 ⊕ С 111 = 0 => С 111 = 1 ⊕ 0 ⊕ 1 ⊕ 0 ⊕ 1 ⊕ 0 ⊕ 1 ⊕ 0 = 0 Таким образом, полином Жегалкина будет равен: F ж = 1 ⊕ A ⊕ E∧A ⊕ A∧D Логическая схема, соответствующая полиному Жегалкина:
