Part 1: The 2-of-3 Voting Circuit

A panel of three judges for the Digital Idol circuit design competition needs a circuit that will indicate whether a digital circuit project will progress to the next level of the competition. A project will advance to the next level if at least two of the judges approve the project with a “Yes” vote. A project will not advance if at least two of the judges reject the project with a “No” vote.

Defining the Logic Function

Complete the truth table in Table 5-1 by indicating whether or not each combination of “No” and “Yes” votes cast by the three judges (called A, B, and C) will approve the project so that it advances to the next level of competition.
