1b)

b) Suppose you need to design a Boolean circuit that checks whether an input 4-bit two's complement number is 5. Show the truth-table for the Boolean function that returns 1 on four input bits A3,A2,A1,A0 if and only if the value of the word A3,A2,A1,A0 interpreted as a two's complement number is 5. (6 marks) Show a Boolean formula that realises this Boolean function and has a few connectives as possible. (6 marks) Show the Boolean circuit that corresponds to your Boolean formula. (2 marks)
