  1. Logic Gates Combinational Logic Circuits

  2. Truth Tables 1 input logic gate has 2 combinations of inputs

  3. Truth Tables 2 input logic gate has 4 combinations of inputs

  4. Truth Tables 3 input logic gate has 8 combinations of inputs How many combinations will a 4 input logic gate have?

  5. NOT gate The NOT gate is sometimes called an inverter. Why? The output is NOT the input Complete the truth table for the NOT gate

  6. AND gate The AND gate allows a decision to be made based on two inputs. The output is on when A AND B are on. Complete the truth table for the AND gate

  7. OR gate The OR gate allows a decision to be made based on two inputs. A B The output is on when A OR B OR BOTH are on. Complete the truth table for the OR gate

  8. NAND gate The NAND gate makes the decision NOT AND The output is NOT applied to the output of the AND gate. Complete the truth table for the NAND gate

  9. NOR gate The NOR gate makes the decision NOT OR The output is NOT applied to the output of the OR gate. Complete the truth table for the NOR gate
