Problem $31-$Digit BCD Full Adder

Learn about Binary Coded Decimal. Check the logic behind a $1-$digit BCD full adder. Come up

with a truth table and logic diagram for the BCD full adder. $($Note : You have to implement the

same question in the lab$).$ A logical diagram should contain block notations $($such as Full Adder,

D Flip$-$Flop, Decoder, Multiplexer$)$ and gate symbols $($such as AND, OR$,$ and NOT$).$
