Serial Adder Introduction, Designing with 74LS Series IC's in Proteus Simulator.

What is serial adder ?

Difference between parllel and serial adder.

How it works?

Implementation using IC's and Proteus File. 

Adavantage and Disadvantage over Parllel adder.

 

What is Serial Adder -

Serial adder is combinational circuit that performs binary addition in serialized manner instead of parllel. 

I will take a example to explain it -

In the avobe example i have taken two decimal numbers . Now assume you have to add these two numbers. What you will do . You will start adding but wait how ?

How to add two numbers ? You will start from taking rightmost digit of both number and add them write down carry and sum . Next you will take 2nd digits from right and add them. this procedure continues till we reached at leftmost digit.

In similar manner, Serial adder works.

We start taking left digits of both number and continue this step. take one digit at a time from both number and add them write sum and transfer the carry to the next.

Advantages and Disadvantages -

Since it add numbers in serial manner, it can add very long bit numbers also. 

It takes more time in comparison to parllel adder.
