BooleanAlgebraBasics

The output of an exclusive-NOR gate is 1,Which input combination is correct?

• A = 1 B = 0

• A = 0 B = 1

• A = 0 B = 0

• none of the above

If 3-input OR gate has 8 input possibilities how many possibilities will result in HIGH output?

• 1

• 7

• 2

• 8

OR gate with schematic "bubbles" on its inputs performs the same functions as___gate.

• NOT

• EX-OR

• NAND

• NOR

How many input and output required for multiplexer ?

• Many input and one output

• One input and many output

• One input and one output

• None of the above

What is the boolean expression for this logic circuit?

• Q = NOT (A OR B)

• Q = NOT A AND B

• NOT A OR B = Q

• Q = (NOT A) OR B

What is the boolean expression for this logic circuit?

• A OR B AND C = Q

• Q = (A AND B) OR C

• Q = A OR (B AND C)

• Q = (A OR B) AND C

In this logic circuit, what is the output Q if the inputs A and C are 1?

• 0

• We can't say

• 1
