How to design 4 bit BCD Adder visualized by 7 segment display Tutorial 01

A BCD adder is a circuit that adds two BCD digits and produces a sum digit also in BCD. BCD numbers use 10 digits, 0 to 9 which are represented in the binary form 0 0 0 0 to 1 0 0 1, i.e. each BCD digit is represented as a 4-bit binary number.
