Logic Circuits

Logic Circuits 

What are logic gates?
Logic Gates are very small electronic decisions-making devices that are fed one or more inputs and give back one output. 

There are 3 basic logic gates:
  • the NOT gate
  • the AND gate 
  • the OR gate
What are truth tables?
A truth table is used to define the output of a logic gate or a logic circuit for all possible combinations of inputs. 

The And,Or and Not Gate.
