Question 9 Design a circuit that has a 3-bit binary input B2, B1, BO (where B2 is most significant bit and BO is least significant bit) and a single output (2) specified as follows: Z=1, when the input is the binary number corresponding to decimal 5, 6 or 7. Z=0, otherwise. Find: (a) the truth Table for Z as a function of B2, B1 and BO; (b) the Karnaugh map for X as a function of B2, B1 and BO; (c) the logic expression for X as a function of of B2, B1 and BO; (d) draw the corresponding circuit.
