Logic Gates

Question 1

Equation

What’s the AND Gate equation?

Example Y = Something

Answer 1

Y = AB

AND Gate Behavior = Y can only be 1 if both A and B are equal to 1; othe

Question 2

Equation

What’s the OR Gate equation?

Example Y = Something

Answer 2

Y = A+B

OR Gate Beh. = Y can only be 1 if either or both A and B are equal t0 1

Question 3

Equation

What’s the NOT Gate equation?

Example Y = Something

Answer 3

Y = A’

NOT Gate Beh. = Y can be equal to one if A is zero, (Opposite)

Question 4

Equation

What’s the NAND Gate equation?

Example Y = Something

Answer 4

Y = (AB)’

NAND Gate Beh. : Y = 1 if A and B are not equal to 1

Question 5

Equation

What’s the NOR Gate equation?

Example Y = Something

Answer 5

Y = (A+B)

NOR Gate Beh. –> Y = 1 if both equal to 0

Exp. (0+0)’ = 1, (0+1)’ = 0, (1+0)’ = 0, (1+1)’ = 0

Question 6

Equation

What’s the Buffer Gate equation?

Example Y = Something

Answer 6

Y = A

Buffer Gate Beh. –> Y is equal to the input

Question 7

Equation

What’s the XOR Gate equation?

Example Y = Something

Answer 7

Y = A (+) B

XOR Gate Beh. –> Y = 1 if A and B are not the same

Exp. (0 0) = 0, (0 1) = 1, (1 0) = 1, (1 1) = 0

Question 8

Equation

What’s the XNOR Gate equation?

Example Y = Something

Answer 8

Y = (A (+) B)’

XNOR Gate Beh. –> Y = 1 if both A and B are the same

Exp. (0 0)’ = 1, (0 1) = 0, (1 0) = 0, (1 1) = 1
