Chpt. 2 Logic Gates

Question 1

(XNOR Gate)
Exclusive-Nor

I.S.O.T.

Answer 1

Both Inputs = Same, Output = True

Input 1 = 0, Input 2 = 0, Output 1

Input 1 = 0, Input 2 = 1, Output 0

Input 1 = 1, Input 2 = 0, Output 0

Input 1 = 1, Input 2 = 1, Output 1

Question 2

(XOR gate)

I.S.O.F.

Answer 2

Both Inputs = Same, Output = False

Input 1 = 0, Input 2 = 0, Output 0

Input 1 = 0, Input 2 = 1, Output 1

Input 1 = 1, Input 2 = 0, Output 1

Input 1 = 1, Input 2 = 1, Output 0

Question 3

(NOT gate)

Answer 3

Inverter/Opposite

Input 1, Output 0

Input 0, Output 1

Question 4

Buffer Gate

What goes in comes out

Answer 4

(Input=True, Output=True)

Input = 1, Output = 1
Input = 0, Output = 0

Question 5

(NOR)

Answer 5

Both False = Output True

Input 1 = 0, Input 2 = 0, Output 1

Input 1 = 0, Input 2 = 1, Output 0

Input 1= 1, Input 2 = 0, Output 0

Input 1 = 1, Input 2 = 1, Output 0

Question 6

(NAND)

Answer 6

Both True = Output False

Input 1 = 0, Input 2 = 0, Output 1

Input 1 = 0, Input 2 = 1, Output 1

Input 1 = 1, Input 2 = 1, Output 0

Input 1 = 1, input 2 = 0, Output 1

Question 7

(OR gate)

Answer 7

Both Inputs = False, Output = False

Input 1 = 0, Input 2 = 1, Output 1

Input 1 = 1, Input 2 = 0, Output 1

Input 1 = 1, Input 2 = 1, Output 1

Input 1 = 0, Input 2 = 0, Output 0

Question 8

(AND Gate)

Answer 8

Both Inputs = True, Output = True

Input 1 = 0, Input 2 = 1, Output 0

Input 1 = 1, Input 2 = 0, Output 0

Input 1 = 1, Input 2 = 1, Output 1

Input 1 = 0, Input 2 = 0, Output 0
