Q1) Design a 3-bit multiplier using AND gates, full adders, or parallel adders. The circuit will take two 3-bit numbers as input and perform the multiplication between them. Attach a screenshot of the circuit that you made on Proteus, showing any 3 combinations of input and their results. Hint: see the given equation below and use the equation to design the circuit. A2 A1 A0 x B2 B1 B0 _____________________ A2B0 A1B0 A0B0 A2B1 A1B1 A0B1 x + A2B2 A1B2 A0B2 x _____________________ P4 P3 P2 P1 P0 P0 = A0B0 P1 = A1B0 + A0B1 P2 = A2B0 + A1B1 + A0B2 + C P3 = A2B1 + A1B2 + C P4 = A2B2 + C Where C is the carry from the previous addition.

Build a 4x2 multiplier, which takes six inputs: - the 4 bits of the first factor: x3, x2, x1, and x0 - the 2 bits of the second factor: y1 and y0 and produces as outputs the six bits of the product: p5, p4, p3, p2, p1, and p0. Your circuit should perform the computation shown below: x3 x2 x1 x0 * y1 y0 ---------------- p5 p4 p3 p2 p1 p0 You circuit should employ the "elementary-school" binary multiplication algorithm that we discussed in lecture. More specifically, you need to compute two partial products: the product of the top number (x3 x2 x1 x0) with the bit y0, and the product of the top number with the bit y1. You then need to add these partial products together in the appropriate way. This circuit should not be built using the minterm expansion principle. Rather, it should be built by combining one or more instances of your 4x1 Multiplier and your 4-Bit Ripple-Carry Adder. See below for information about adding those components to your circuit.
