Detection of redundant function,self-negative function and self-dual function based on tabular method

Redundant function,self-negative(SN) function and self-dual(SD) function have many advantages.The detection of redundant function,self-negative(SN) function and self-dual(SD) function is of importance in the research for them.Based on the definitions and properties of redundant function,self-negative(SN) function and self-dual(SD) function,they are detected by using tabular method which are based on Boolean expression,RM and CRM.Therefore,the methods of detecting redundant function,self-negative(SN) function and self-dual(SD) function are presented.Furthermore,the simplicity and programmability of the tabular method are discussed
