INTRODUCTION TO THRESHOLD LOGIC DERTOUZO’S 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) Threshold logic
Unate Function: (example) Threshold logic
(Ex) Threshold logic
(Ex) Threshold logic
example 1: Threshold logic
Example 2: Threshold logic
Write bi’s in descending order of magnitude Determine a’s from the Dertouzo’s table Threshold logic
XOR Realization Threshold logic
ELEMENTARY PROPERTIES Threshold logic
ELEMENTARY PROPERTIES Threshold logic
example: Five variable mirror symmetry problem Threshold logic
DERTOUZOUS’ TABLE (Threshold function upto five variables) Threshold logic
(Dertouzous’s table) Threshold logic
