The implementation of the logical gates are performed by the rules of the boolean algebra, and based on the combinations of the operations OR, AND and NOT. Explanation: Yacc (for "yet another compiler compiler. The only time we use it is to pull it low in order to force Q to a logic zero output. Loading Logic Gates v2. Available operators and bitwise AND, bitwise OR and bitwise XOR (eXclusive OR). These circuits can be classified as combi-national logic circuits because, at any time, the logic level at the output depends on the combination of logic levels present at the inputs. If any input (s) is “low” (0), the output is guaranteed to be in a “low” state as well. Bitwise Operations, is the logical operations between two binary digits or change the value of individual bit based on the bitwise logic of the operator.
