Question: Design a one digit BCD adder using two 4-bit adders (TTL7483). Remember that the value of a BCD digit cannot exceed 9 (1001). If the sum of the two added digits is greater than 9, a correction factor of 6 (0110) should be added to the sum bits and a carry of 1 is generated. Your circuit should include the logic needed to detect whenever the sum is greater than 9 so that the correction can be added in. Use one of the 4-bit adders to add the two digits and the other one to add the correction factor if needed.
