1. presently, many electrical appliances are able to receive commands to carry out its specific tasks.
2. these appliances receive input from the environment. make a decision on the input & then give out the
result as an output.
3. an electronic device that can be used to perform these tasks is called a logic gate.
4. in a logic gate, there may be several inputs or may be a single input. But the output would be
only one.
5. the logic gates are to automatically switched "ON" or "OFF".
6. the binary digits "1" & "0" are used to represent "ON" & "OFF" states respectively.
7. all possible situations of the inputs & outputs of the logic gates will be listed in a truth table.
8. the total number of combined output,N that can possibly be obtained from n variables of the inputs can be calculated using the formula N = 2n
