Nand and Nor Gates

What is the output of a NOR gate when one input is 1 and the other is 0?

• 0

• 1

• Undefined

• Depends on the impedance

• NAND

• NOR

• OR/AND

If I turn on one switch, and turn the other on, which gate would output FALSE?

• AND

• NAND

• XNOR

• OR

Which situation would make the most sense to use an NOR gate?

• Sound the alarm if smoke it detected. Sound the alarm if the manual lever is pulled. Sound the alarm if both happen.

• The missile should launch when both buttons are pushed.

• The night light should turn on when the regular lights are OFF (no light detected).

• Do not turn on the sprinklers it rained today or there is a football game today.

What is the output of a NAND gate when both inputs are 1?

• 0

• 1
