Thus there are only 2 essential prime implicants , which shall exist in all possible groupings of 1's at 0000 and at 1010 0 votes 0 votes Please log in or register to add a comment.

EPI is also a prime implicant which have atleast 1 minterm covered by only one PI. Every possible combination of minterms is PI. In your case its is 6 PI and 2 EPI Ravi kumar singh answered Jan 26, 2019 Ravi kumar singh comment Share Follow See all 0 reply Please log in or register to add a comment.
