DLD: DATA LOGIC DESIGN - ASSIGNMENT BCD Adder/ DECIMAL ADDER BCD binary numbers represent Decimal digits 0 to 9. A 4-bit BCD code is used to represent the ten numbers 0 to 9. Since the 4-bit Code allows 16 possibilities, therefore the first 10 4-bit combinations are considered to be valid BCD combinations. The latter six combinations are invalid and do not occur. BCD Code has applications in Decimal Number display Systems such as Counters and Digital Clocks. BCD Numbers can be added together using BCD ...
