INTRODUCTION TO THRESHOLD LOGICDERTOUZOS METHOD FOR THE REALISATION OF THRESHOLD LOGIC

Threshold logic

OR gate:

Threshold logic

UNATE FUNCTIONS

Threshold logic

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

Non-Unate function: (example)
