Question: design a 4 - bit adder. the inputs will be 2 4 - bit numbers A ( a 3 a 2 a 1 a 0

design a 4-bit adder. the inputs will be 24-bit numbers A( a3 a2 a1 a0) and B(b3 b2 b1 b0). The output will be a 5-bit number S(s4 s3 s2 s1) Need to draw a block diagram and a circuit for design. Explain how the 4-bit adder functions. Use the decimal A=12 and B=7 in your explanation, converting them to binary first. finally demonstrate that the results 5-bit binary number is correct by converting it back to a decimal number.
