CSI Task 1.
(a) Consider the circuit below:

-El
Three gates have been taken out of the circuit. Place the gates in the circuit, you choose where and draw the completed circuit (you can copy this diagram into your submission, see Blackboard for the Word file). Then, write X as an unsimplified Boolean expression, and as a truth table (the truth table must show intermediate values) (5 marks each, 10 marks total)
(b) You must design a combinational logic circuit to the top four countries from the list you wish to visit.
The circuit has three inputs, forming the three bits of a binary number that represent the eight countries (O=USA, 1=France, 2=Germany, 3=Italy, 4=Spain, 5=Scotland, 6=Netherlands, 7=Japan) • The circuit is to have an output of 1 for the 4 countries out of the eight that you wish to visit (you are to choose the countries.) • The output will be 0 for the rest of the countries.
