Connection Procedure:

  • Insert IC #[74LS0] (NOT)[74LS08] (AND)[74LS32] (OR)  in the bread board.
  •  Connect Pin #7 to Ground and pin#14 to the Power Supply.
  • Connect Pin #1 of NOT gate to Pin #2 of NOT gate ( short circuit ).
  • Connect Pin #1 of AND gate to the First input A.
  • Connect Pin #2 of NOT gate to Pin #2 os AND gate th the Second input Switch B.
  • Connect Pin #4 of AND gate to third input switch c.
  • Connect Pin #5 of ANG gate to  third input switch c.
  • Connect Pin #3 and Pin#6 of the AND gate to pin #1 and pin # Or gate.
  • Connect Pin #3 of OR gate to the output switch Led.
  • Verify the truth table Possibilities.

Connection procedure Using gate:


  1. Connect IC #74LS00 to the bread board.
  2. Connect Pin # to AND and Pin#14 to power Supply E.
  3. Connect Pin #4 as First input Switch A.
  4. Connect Short Circuit pin #1 and Pin #2 and takes second input Switch B.
  5. Connect pin #3 to pin #5 Directly.
  6. Connect pin #9 to pin #4 Directly.
  7. Connect Pin  #10 to directly as third input switch.
  8. Connect Pin #6 tp Pin12 and Pin #8 to Pin #13.
  9. Connect pin #11 to the Output Switch Led.
  10. Verify all the truth table Possibilities.

 

RESULT:

 Thus the Karnaugh-Map Simplification For the given Function is Verified.
