  3. We now write the Boolean functions for the carry outputs of each stage and substitute each C; its value from the previous equations:

  4. BCD ADDER C=K+Z8Z4+Z8Z2 When C=1 , it necessary to add 0110 to the binary sum and provide an output carry for the next stage . A BCD adder that adds two BCD digits and produces a sum digit in BCD is shown in fig. The two decimal digits , together with the input carry , are first added in the top 4-bit adder to produce the binary sum . When the output carry is equal to zero , nothing is added to the binary sum . When it is equal to one , binary 0110 is added is added to the binary sum through the bottom 4-bit adder
