Review Question 1. Draw chip connection of XOR gate and NOT gate and write comment on their operation 2. Fill up the blanks: (a) XOR is the inverse of (b) Boolean equation for 3 inputs XNOR gate is (c) If both input of XOR is low or high, its output is (d) IC No. of 2 inputs XOR gate is (e) NOT gate is also called (1) Boolean equation for NOT gate is 3. Write a Boolean expression for the following statement: X is a l only if A is I and B is a I or if A is a 0 and B is a 0 4. Design a combinational Logic circuit which compares two bit input numbers, 5. A manufacturing plant uses two tanks to store a certain liquid chemical that is requires in a manufacturing process. Each tank has a sensor that detects when the chemical level drops to 25% of full. The sensor produces a 5v level when the tanks are more than one-quarter full. When the volume of chemical in a tank drops to one- quarter full, the sensor puts out a OV level. It is required that a single LED on an indicator panel show when both tanks are more than one-quarter full Design a logic circuit to implement the above.
