**Que 1. Design and explain the logic and circuit of a 4-bit magnitude comparator. **

| **OR** |

**Design a 4-bit magnitude comparator using one bit comparator modules.**

| **OR** |

**Draw and explain the 4-bit magnitude comparator.**

4-bit magnitude comparator using logic gates.

**Que 2. Design the following boolean function using a 4 x 1 multiplexer.** **P(A, B, C, D) = Σm(0, 1,3,4, 8, 9, 15)**

**Que 3. Using a decoder and external gates, design the** **combinational circuit defined by the following three boolean** **functions:**

**Que 4.Draw the logic diagram of a two to four line decoder using NOR gates only. **

**Que 5.Describe half adder and full adder in brief. Implement the circuit using logic gates.**

| **OR** |

**Design a full adder using two half adders.**

**Full adder circuit using 2 half adder**

**Que 6. Draw a BCD adder circuit and explain its working.**

| **OR** | **Draw a decimal adder to add BCD number.**

**Answer**

1. A BCD adder is a circuit that produces a Bum digit that is also a BCD digit by adding two BCD digits simultaneously. 10 symbols make up BCD numerals (group of 4 bits 0000 to 1001). The following is what a BCD adder circuit must be able to achieve, and it is depicted in Fig.

2.Add two 4-bit BCD numbers using straight binary addition.

3. If a 4-bit total is 9 or less, it is a valid BCD number and doesn’t require rectification.

4. The 4-bit total is an invalid BCD number if it exceeds 9 or if a carry is produced from it. The final step is to add the digit 6 (0110)_{2} to the total to create the correct BCD symbols.
