LOGIC GATES

LOGIC GATES

1. AND

   • The AND gate tells us if both of the inputs are 1, by outputting 1, otherwise it outputs 0.
   • The truth table shows two inputs, A and B, and all the possible combinations of values for A and B

2. NOT

   • The NOT gate is a very simple gate - if 0 is input then it outputs 1 and if 1 is input it outputs 0.
   • We express this relationship between input and output as a truth table

3. OR
