There are seven judges at “Engineers Got Talent”. Each one of them vote if to continue with the candidate to the next round or to dismiss him.
X0, X1, …. ,X6
Xi = 0 – Dismiss
Xi = 1 – Keep
A candidate is dismissed if at least five judges decide to. Design a system that gets the judges votes ( X0, X1, …. ,X6 ) and the output is 1 if the candidate is dismissed and 0 if continues to the next round.
You have the following to your use: Four Full Adders, 3 to 8 Decoder and an OR gate.
