Question

**8. Create a Truth Table for the following logic expression:**

\( \overline{\overline{AB} + \overline{CA} + \overline{CB}} \)

**Explanation:**
- This is a logical expression involving variables A, B, and C.
- The expression uses negation (indicated by the overline) and logical OR operations (indicated by the plus sign).
- It requires the creation of a truth table that evaluates all possible combinations of inputs A, B, and C to determine the truth value of the expression.

Expert Solution

Step 1

Explanation:

As there are three variables so there will be 23=8 cases for the given expression.
The addition function computes 1, if any of one input value is 1, it computes 0, only if all the input values are 0.
The multiplication computes 1, if all the values are 1, otherwise computes 0.
The negation or bar function simply reverse the input values.
The below tables shows the truth table value for the given expression.
