The implementation of such a formal system for propositional logic by a computer is relatively straightforward. One method is to incrementally construct a truth table for a sentence from its components by enumerating all possible combinations of truth values for the symbols occurring in the sentence....

1.1.2 The Logic Operations The basic,ve logic operations we will use in this text are given in Table 1.2 for every possible truth value of underlying component statements.We say that the operation∼takes one argu-ment (not to be confused with the colloquial meaning of the term), that arg...
The only pair of truth values for P and Q that makes the implication false is when P is true and Q is false. All other combinations of truth values for P and Q result in a value of true for the implication. Here is the truth table for the implication P⇒Q: Code...
When we think about the truth table of an “If A, then B” statement, we can observe that this statement is true three times out of four. This is also a feature of the logical connective or. So, it is conceivable to suspect a logic relation between the two. We can compare “If A...

This includes a description of Boolean algebra, the mathematical language of digital electronics, and the logic gates used to implement Boolean functions. Also covered are the ‘tools’ of digital electronics such as truth tables, timing diagrams and circuit diagrams. Finally, certain concepts such ...
