Logic Gates Interview Question Answer - 2

16	What is other name of NAND gate?
	Bubble OR gate, Negative OR gate
17	When the NAND gate can be used as an inverter?
	The NAND gate is used as an inverter if all input terminals are connected together and applying input to input.
18	What is bubble AND gate?
	Bubble AND gate The AND gate with bubble inputs is called as bubble AND gate.
19	Write other name of NOR gate.
	Bubble AND gate, Negative AND gate
20	Why the NOR gate is called as active low AND gate?
	Active low AND gate The NOR gate is called as active low AND gate because the output is at high state when all inputs are at low states.
21	What is condition for high output in the EX – OR gate?
	The output of the EX – OR gate becomes high if and only one input at logic high state.
22	Which gate is known as anti – coincidence gate or inequality detector?              OR Why the EX – OR gate is known as anti – coincidence gate?
	Anti – coincidence gate The output of the EX – OR gate is high only when the inputs are not equal therefore the EX – OR gate is also called as anti – coincidence gate or inequality detector.
23	Which gate is known as coincidence gate or equality detector?               OR Why the EX – NOR gate is known as coincidence gate?
	Coincidence gate The output of the EX – NOR gate is high only when the inputs are equal therefore the EX – NOR gate is also called as coincidence gate.
24	How EX – NOR can be used as inverter?
	The EX – NOR can be used as inverter if one of its two inputs is connected to logic 0.
25	How EX – OR can be used as inverter?
	The EX – OR can be used as inverter if one of its two inputs is connected to logic 1.
26	Which gates are used for enable or inhibit operation?
	OR, NOR, AND and NAND
27	When the outputs of the AND and OR gates produce constant low?
	The outputs of inhibit AND and OR gates produce constant low.
28	When the outputs of the NAND and OR gates produce constant high?
	The outputs of inhibit NAND and OR gates produce constant high.
29	Whether the operation of the logic gate is affected by pulsed level instead of constant logic level?
	No
30	How many output the logic gates consist of?
	Only one
31	How many input the EX – OR and EX – NOR gate does not consists?
	Three or more
