What is the definition of a parallel adder?
It is a digital circuit that produces the arithmetic sum of two binary number .It can be constructed with the full adders connected in cascade,with the output carry from each full adder connected to the input carry of the next full adder in the chain.

How an adder subtracter works?
An adder-subtractor is a digital circuit that can perform both addition and subtraction operations on binary numbers. It typically uses a full adder circuit along with a method to manipulate the sign of the second operand for subtraction. This is often achieved by inverting the bits of the second number (using a NOT gate) and adding one to it, effectively implementing the two's complement method for subtraction. The circuit then processes the inputs to yield the desired result, either adding or subtracting, depending on the control signals provided.
Construct BCD to excess3 code using full adder circuit?
4 full adders will be used BCD is a 4 bit code. Each bit of the BCD number will be an input of each full adder. input 1 in first FA. 1 in second and 0 in the last to FA's
Design a binary to excess-3 converter?
A binary to excess-3 converter can be designed using combinational logic. The converter adds 3 (or 0011 in binary) to the 4-bit binary input. The logic circuit can be implemented using a 4-bit binary adder, where the binary input is fed into one input of the adder, and the constant binary value 0011 is fed into the other input. The sum output of the adder provides the corresponding excess-3 code.
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
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 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.
