3) Construct a BCD adder using the 4-bit binary full adders. .In a binary coded decimal (BCD) system, 4 bits are used to represent a decimal digit from 0 to 9. For example, Decimal - 37 is written as BCD 0011 0111 .Since each decimal digit cannot exceed 9, the maximum BCD sum can be 19-9+9+ 1(Carry in). 6. Laboratory Report: As usual, please follow the laboratory report form. Draw the pin diagram of Adder - 7483. In your report, discuss the operation of the circuits and the verification of the function of each
