1. How do you convert a XOR gate into a buffer and a inverter (Use only one XOR gate for each)?

Answer

2. Implement an 2-input AND gate using a 2x1 mux.

Answer

3. What is a multiplexer?

Answer

4. What is a ring counter?

Answer

5. Compare and Contrast Synchronous and Asynchronous reset.

Answer

6. What is a Johnson counter?

Answer

7. An assembly line has 3 fail safe sensors and one emergency shutdown switch.The line should keep moving unless any of the following conditions arise:

(1) If the emergency switch is pressed

(2) If the senor1 and sensor2 are activated at the same time.

(3) If sensor 2 and sensor3 are activated at the same time.

(4) If all the sensors are activated at the same time

Suppose a combinational circuit for above case is to be implemented only with NAND Gates. How many minimum number of 2 input NAND gates are required?

Answer

8. In a 4-bit Johnson counter How many unused states are present?

Answer

9. Design a 3 input NAND gate using minimum number of 2 input NAND gates.

Answer
