Logic Gates

The Or Gate has this number of ON/1 Outputs

• 1

• 2

• 3

• 4

Logc Circuits are formed of

• AND Gates

• OR Gates

• NOT Gates

• All of the above

The And Gate is represented algebraically by

• *

• +

• -

• %

The only gate that has 1 input and 1 output is

• AND

• OR

• XOR

• NOT

The OR Gate has Algebraic presentation of

• +

• *

• -

• None of the above

(C AND D) OR (NOT(A OR B)) = Q, If A=1, B=1, C=0 and D=1, what does Q equal?

• 0

• 1

A truth table lists every possible combination of input and the resulting output

• True

• False

The difference between OR and XOR Gate

• both have 3 inputs

• The output of the XOR in case of two ON inputs is 0

• OR has 2 inputs and XOR has 3 inputs

• They are similar in everything

Building blocks

• Save time and money

• are very expensive

• do not carry the data

• None of the above

The output of a ________ gate is only 1 when both inputs are 1.

• OR
• NOT
• NAND
• AND
