What are the single input logic gates?
NOT
BUF
Just keeps the variable as is
What are the two-input logic gates?
AND
OR
XOR
Outputs a 1 only one exactly one of its inputs are true
NAND
NOR
XNOR
Outputs a 1 only when both of its inputs are the same
What are the multiple input logic gates?
NOR3
Takes 3 values and only outputs a 1 if all values are equal to 0
What do discrete voltages represent?
1 and 0
0 = ground or 0 volts
1 = V or 5 volts
Is 4.99 volts a 0 or a 1?
It is a 1 because it is closer to 5 than 0.
What is noise?
Anything that degrades the signal.
Resistance, power supply noise, coupling to neighboring wires, etc.
What is the static disipline?
With logically valid inputs, every circuit element must produce logically valid outputs.
Use limited ranges of voltages to represent discrete values
When are two logic circuits equivalent?
If for all combinations of the inputs, their outputs are the same.
