We need a logic circuit that gives an output X that is high only if a given hexadecimal digit is even (including 0) and less than 7. The inputs to the logic circuit are the bits B8, B4, B2, and B1 of the binary equivalent for the hexadecimal digit. (The most significant bit is B8, and the least significant bit isB1.) Construct a truth table and the Karnaugh map; then, write the minimized SOP expression for X.
