boolean logic (10)

• NOT


  one input

  output opposite of input signal

  eg.

  input - 0

  output - 1
• AND


  two inputs

  both inputs need to be on (1)

  eg. input - 1,1

  output - 1
• OR

  two inputs

  only one input need to on (1)

  eg. input - 1,0

  output - 1
• NAND


  two inputs

  if both inputs are on (1) the output is off (0) otherwise the output is (1)

  eg. input - 0,0

  output - 1
• NOR


  two inputs

  if one input is on (1) the output will be off (0) otherwise the output is (0)

  eg. input - 0,1

  output - 0
• XOR


  two inputs

  if both inputs are the same the output will be off (0). if one of the inputs are on (1) then the output is off (0)

  eg. input - 0,1

  output - 1
