2.4 Computational Logic

1. Logic Diagrams

   • Logic Diagrams ...
   • Simple
     • NOT
       • Outputs the opposite of the input
     • AND
       • Both the inputs must be 1 to output 1
     • OR
       • One of the inputs must be 1 to output 1
   • Logic Diagrams can be combination of ANDs, ORs, and NOTs

2. Applying computing-related mathematics:

   • +
   • --
   • *
   • /
   • Exponentiation (^)
   • MOD
   • DIV

3. Truth Tables

   • The behaviour of each logic gate can be represented with a truth table.
   • They can be used to work out the output of complicated logic gates.
