Why you use half adder after the arrival of full adder?
The full adder takes care of everything, A, B, CarryIN, Sum, and CarryOut. I don't see why you would need a half adder after using a full adder, unless you were trying to process look-ahead carry, but that requires more than just a half adder.
How can you draw a 4 bit full adder using 1 bit full adder?
The 1 bit full adder has three inputs, A, B, and CarryIn. It has two outputs, Result and CarryOut. To connect multiple 1 bit full adders together, bus the A and B inputs into their respective buses, bus the Result outputs into its bus, connect the low order bit's CarryIn to LogicFalse, and daisy chain each bit's CarryOut into the next bit's CarryIn. Use the last bit's CarryOut as overall CarryOut.
Design Excess 3 to bcd using full adder?
you must use HA
Why full adder is better then half adder?
Full adder is better than half adder because in half adder we can perform operation on only two digits and in full adder we can perform operation on three binary digits.
Difference between adder and parallel adder?
1.serial adder add bits serially but parallel adder add bits at the same time . 2.serial adder depends on previous outputs but parallel adder does not depends on previous outputs . 3.parallel adder takes less time to execute compared to serial adder.

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

How do you make BCD binary up down counter with a 4-bit adder and a register?
I wants to know the advantages of 4 Bit BCD/Binary UP/DOWN
How many don't cares are there in a BCD adder?
5 per 4 bits, so anything over, but not including, 1001
How i can Design a BCD-to-excess-3 code converter with a BCD-to-decimal decoder and four OR gates?
i dont know 1001+1001 - Constructing a BCD-to-excess-3-code converter with a 4-bitt adder we know that the excess-3 code digit is obtained by adding three to the corresponding BCD digit. To change the circuit to an excess-3-to-BCD-code converter we feed BCD-code to the 4-bit adder as the first operand. Then feed constant 3 as the second operand. The output is the corresponding excess-3 code. To make it a BCD to excess-3 converter, we feed the 2's complement of 3 as the second operand. - Constructing a BCD-to-excess-3-code converter with a 4-bitt adder we know that the excess-3 code digit is obtained by adding three to the corresponding BCD digit.

How does a half adder work?
A full adder has three inputs - A, B, and CarryIn from the prior stage. It generates a Result and a Carryout with the truth table... ABC-RC 000-00 001-10 010-10 011-01 100-10 101-01 110-01 111-11 The adder can be a ripple adder, in which the propogation delay depends on the carry "rippling" through the logic, or it can be a look-ahead-carry type, which has constant propagation delay time, at the expense of more logic.
What does BCD in BCD Travel stand for?
The name BCD doesn't stand for anything according to Bernd Rittinger, BCD Travel Director of Operations.
