Logic Circuits

What is a logic circuit?

  • A logic circuit performs logical operations on binary information

  • Logic gates are core components of logic circuits

  • Based on the arrangement of logic gates and the input signals, the circuit performs a specific function

  • A logic diagram is a visual representation of a combinations of logic gates within a logic circuit

  • Brackets are used to clarify the order of operations

  • An example logic diagram for the Boolean expression Q = NOT(A OR B) would be:

logic circuit1
  • In the logic diagram above, the inputs are represented by A and B

  • P is the output of the OR gate on the left and becomes the input of the NOT gate

  • Q is the final output of the logic circuit

Example of combining logic gates

10-boolean-logic
  • P = (A OR B) AND NOT C
