Avik Kumar Choudhury, SUNIL RANJAN DAS · International Journal of Control · 1965
A method of determination of one of the minimal prime implicant covers of switching functions by utilizing the properties of the connected cover term matrices has been presented in the paper. The essential prime implicants of the function have been recognized by making a table (called cover table) in which all the minterms of the function appear in a row and below each of the minterms the set of prime implicants covering it occurs in a column. After the selection of the essential prime implicants, the remaining columns of the table have been arranged in a number of open connected cover term matrices from which one of the minimal prime implicant covers of the function has been obtained readily. The number of enumerations involved in finding the minimal solutions of functions having cyclic tables has been reduced in the method.
