Lab 7 BCD Adder/subtractor& Magnitude Comparator ICs: Two 7483 (4-bit binary adder), 7408 (2-input AND),7432(2-input OR), 7486 (XOR), 7404 (Inverter) BCD Adder: You are to design a circuit that adds two BCD digits. The inputs to the circuit are BCD numbers A and B, plus a carry-in, cin. The output should be a two-digit BCD sum. Build your BCD adder using two 4-bit binary adders and possibly some other logic gates. 1· In the BCD representation system each digit is encoded into its binary equivalent with four (4) bits. For the arithmetic addition of two decimal digits in BCD, the maximum value that may be produced as the result is 9+9+1 – 19 (two largest operands plus the carry). If we try to add two decimal digits in BCD with a 4-bit adder we will get a binary sum ranging from 0 to 19. When the binary sum is less than or equal to 9, it also correctly represents the sum in BCD. When the binary sum is greater than 9, however, it does not represent the correct BCD sum. The sum in BCD is to be obtained by adding 6 to it. Perform the steps given below: Perform the following addition in BCD as explained above: a. 1)7+4 2) 3+2 3)9+9 The above examples be done to perform the conversion correctly b.
