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
|
