(a) Figures 1 shows a 4-bit unsigned multiplication. Design a 4-bit variable- constant unsigned multiplier where the constant input b = 13. Show all your design steps and draw the logic diagram using the minimum number of components. аз a2 a1 ao b3 b2b bo azbo a boabo a bo azbab abi aob a3b2a2b2ab2 a,b2 a3b3a2b3 abg abg P P6 PS P4 P3 P2 ро Fig. 1 (7marks) PI (b) Redesign the circuit in (a) using a ROM.
