NOR Gate
Project #645
OBJECTIVE: To demonstrate the operations of the “exclusive
or” XOR gate.
XOR Gate
The NOR gate works the opposite of the OR. Using the chart, set the
switches (S1 & S2) to the different states. The display (D7) lights the
letter “L” when either switch is turned on.
In an XOR gate the output “Q” is only high when inputs “A” or “B” is set
high (1).
Using the chart, set the switches (S1 & S2) to the different states. The
display (D7) lights the letter “H” only when either switch is turned on.
