Figure 2-5a. AND gate logic with two inputs, Truth Table.
You will soon be able to recognize the Truth Table for the other types of logic gates without having
to look at the logic symbol.
Q1. What is defined as "the science of reasoning?"
Q2. With regard to computer logic circuits, what is meant by "complement?"
Q3. What are the complements of the following terms?
Q4. If logic 1 = - 5 vdc and logic 0 = - 10 vdc, what logic polarity is being used?
Q5. If logic 1 = +2 vdc and logic 0 = - 2 vdc, what logic polarity is being used?
Q6. If logic 1 = - 5 vdc and logic 0 = 0 vdc, what logic polarity is being used?
Q7. What is the Boolean expression for the output of an AND gate that has R and S as inputs?
Q8. What must be the logic state of R and S to produce the TRUE output?
Q9. How many input combinations exist for a four-input AND gate?
