Q$1.$

In many computers and other types of processors, adders

are even used to calculate addresses and related activities

and calculate table indices in the ALU and even utilized

in other parts of the processors. For this purpose, an

electronic circuit is needed to design that can add two

single bit digits and one carry bit which is the overflow

of the sum of the previous stage of addition and outputs

the sum and the carry. Applying the concept and

information of logic gates and Boolean expression design

the circuit and prepare the related Boolean expressions

and truth table.
