Build a circuit th using a 4 bit adder, 4 XOR gates, and the logic simulator. You h at carries out 2's complement addition and subtraction operations ave a 4 bit 2's complement number system. Carry out the 2's complement addition or subtraction operation on two numbers A and B in this system, and write your answers into the boxes provided! You must write down all intermediate carries to get marks for these exercises For each question, write down whether or not the operation gives an overflow or not!
