Full adder circuit using 2 half adder
Que 6. Draw a BCD adder circuit and explain its working.
| OR | Draw a decimal adder to add BCD number.
Answer
1. A BCD adder is a circuit that produces a Bum digit that is also a BCD digit by adding two BCD digits simultaneously. 10 symbols make up BCD numerals (group of 4 bits 0000 to 1001). The following is what a BCD adder circuit must be able to achieve, and it is depicted in Fig.
2.Add two 4-bit BCD numbers using straight binary addition.
3. If a 4-bit total is 9 or less, it is a valid BCD number and doesn’t require rectification.
4. The 4-bit total is an invalid BCD number if it exceeds 9 or if a carry is produced from it. The final step is to add the digit 6 (0110)2 to the total to create the correct BCD symbols.
