truth table
a b out carry
0 0 0 0
0 1 1 0
1 0 1 0
1 1 0 1
it may be noted that out can be achieved with XOR gate
and carry with an AND gate
for a two bit adder you need twice the hardware
if you can add in decimal with pencil and paper perhaps binary will be easier to understand

Advantages of fast adder over parallel binary adder?
serial adder: 1) Slower 2) It uses shift registers 3) IT requires one full adder circuit. 4) It is sequential circuit. 5) Time required for addition depends on number of bits. Parallel adder: 1) Faster 2) It uses registers with parallel load capacity 3) No. of full adder circuit is equal to no. of bits in binary adder. 4)It is a combinational circuit 5)Time required does not depend on the number of bits
What is carry propagation time in adder circuit?
The worst case time between:application of valid new stable values on the adder's inputsthe development of the valid new stable carry on the adder's carry output
Binary adder-subtractor combine circuit?
Switch Mode (SM) is a control input to the circuit to switch between addition or subtraction operations. Adder When SM = 0 the circuit is equivalent to Binary Adder. A + B (bit ) XOR 0 = A + B (bit) Subtraction When SM = 1 the circuit is equivalent to Binary subtraction. A + B (bit ) XOR 1 = A + invert(B (bit)) 'B' input becomes inverted in this case.
What are the advantages of half and full adder circuit?
Do you mean :- how to get full adders by using half-adders? For this question refer following answer - A full-adder can be obtained by combining two half-adders and one or gate. Details on full-adder and half-adder can be referenced from following link http://www.fullchipdesign.com/fulladder.htm
How do you draw the circuit of excess 3 adder?
This is something that should only be done by a professional. Take it into a mechanic in order to avoid any issues.
What is half-adder circuit?
The circuit which adds two single bit binary numbers and produce a sum and carry is a half adder circuit.
What is the difference between Serial and Parallel Adder?
Some key differences between a Serial and Parallel Adder are that a Serial Adder is slower, a Parallel adder is a combinational circuit and the time required for addition depends on the number of bits in a Serial, but not a Parallel. A Serial Adder is a sequential circuit while a Parallel is a combinational circuit.
Application of full adder?
full adder reduces circuit complexibility
Is parallel adder a sequential circuit or combinational circuit?
Combinational chutiye
What kind of a adder is IC 7483?
IC 7483 is a 4-Bit Full Adder Circuit.

Can full adder become half adder?
No. A full adder is two half adders with a carry circuit to combine the two carries together.
Why ripple carry adder is used?
A ripple carry adder needs a much less complicated circuit, than other adder topologies.
