1

What are the single input logic gates?

  • NOT

  • BUF

    • Just keeps the variable as is

New cards
2

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

New cards
3

What are the multiple input logic gates?

  • NOR3

    • Takes 3 values and only outputs a 1 if all values are equal to 0

New cards
4

What do discrete voltages represent?

1 and 0

  • 0 = ground or 0 volts

  • 1 = V or 5 volts

New cards
5

Is 4.99 volts a 0 or a 1?

It is a 1 because it is closer to 5 than 0.

New cards
6

What is noise?

Anything that degrades the signal.

  • Resistance, power supply noise, coupling to neighboring wires, etc.

New cards
7

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

New cards
8

When are two logic circuits equivalent?

If for all combinations of the inputs, their outputs are the same.
