  1. INTRODUCTION TO THRESHOLD LOGIC DERTOUZO’S METHOD FOR THE REALISATION OF THRESHOLD LOGIC Threshold logic

  2. OR gate: Threshold logic

  3. UNATE FUNCTIONS Threshold logic

  4. Threshold functions are functions which can be realized with the help of one threshold gate Unate functions are either positive or negative in a particular variable but not both.(in a simplified boolean function) Threshold logic

  5. Non-Unate function: (example) Threshold logic

  6. Unate Function: (example) Threshold logic

  7. (Ex) Threshold logic
