Build a circuit that takes four bits as input: W, X, Y, Z. Treat WX as a 2-bit unsigned binary  number, and treat YZ as a second 2-bit unsigned binary number. Your circuit should generate  the output corresponding to the product of WX and YZ. You will need 4 bits of output for this  problem. For example, if your input was 1011, your inputs correspond to 2 and 3. That product is 6, so  your output will be 0110. Create a truth table for this problem, show all k-maps and minimizations, and build the  corresponding (minimized) circuit. Use XOR, XNOR, NAND, and NOR as appropriate if it  reduces the number of gates used.

Question

Build a circuit that takes four bits as input: W, X, Y, Z. Treat WX as a 2-bit unsigned binary 
number, and treat YZ as a second 2-bit unsigned binary number. Your circuit should generate 
the output corresponding to the product of WX and YZ. You will need 4 bits of output for this 
problem.
For example, if your input was 1011, your inputs correspond to 2 and 3. That product is 6, so 
your output will be 0110.
Create a truth table for this problem, show all k-maps and minimizations, and build the 
corresponding (minimized) circuit. Use XOR, XNOR, NAND, and NOR as appropriate if it 
reduces the number of gates used.
