If both inputs have to be TRUE, which truth table represents that logical relationship?
If both inputs have to be FALSE, which truth table represents that logical relationship?
Which logic gate outputs TRUE if one, but NOT BOTH inputs is true?
When an input to a logic chip has no connection to positive or negative, the logic gate will freak out. These switches are an example of that because they are missing....
Floaters
Pull Down Resistors
LEDs
Pull Up Resistors
When an input to a logic chip has no connection to positive or negative, the logic gate will freak out. That condition, not being connected is called:
Pulling Down
Drifting
Floating
Lifting
Logic gate circuits require lots of positive and negative connections. The thing they connect to is called a...
Breaker
Shuttle
Bus
Array
The left side is connected to
5V Positive
The "ground" negative
An electric Jelly fish
A ray
Which situation would make the most sense to use an AND 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.
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.

If I turn on one switch, and turn the other off, which gate would output TRUE?
AND
NOR
XNOR
OR
If I turn on one switch, and turn the other on, which gate would output FALSE?
AND

If I turn off one switch, and turn the other off, which gate would output TRUE?
AND
NOR
XOR

The circle at the end of some gates means NOT. How does adding the the word NOT change the outputs?
It changes one output to false.
It reverses all the outputs, changes 0 --> 1 and 1 -->0.
It makes all inputs true.
It makes all inputs false.
Which gate outputs true only if the inputs are both true, or both false?
AND
NOR
XNOR
OR
Which 2 gates only have 1 input?
