Question

The space shuttle was controlled by three on-board computers; binary output from these three computers was compared and a majority vote was required for certain actions to take place. Find a truth function, a Boolean expression, and a logic network that outputs the majority vote of the three input values

Answer 1

Answer:

Please kindly check explaination

Explanation:

Let the output from three on board computers be A, B and C respectively.

The output should be one only if more than half i.e. 2 or more than 2 on board computers give output as 1

So the output for Majority vote for this system would be as follows

MajorityOutput = AB + AC + BC .

The truth table and logic gate function is represented in images.
