Best answer 1 votes 1 votes Considering two input nand gates. if we connected two sorted input NAND gates it will give A. 1st NAND will give A' and 2nd will give A. two nand gates. answer. arvin answered Sep 7, 2018 selected Sep 7, 2018 by srestha arvin comment Share Follow See all 2 Comments See all 2 2 Comments reply saumya mishra commented Sep 7, 2018 reply Follow Share Check this https://gateoverflow.in/41842/isro2016-7 0 votes 0 votes arvin commented Sep 7, 2018 reply Follow Share @saumya see the question has asked for minimum number of nand gates to realize the expression. and there we dont need any gate we will simply use a wire... but here the question says to represent an A and here you could have done it with one nand gate also if u take A' as input... but we have to consider pure values to find the minimum realization with gates and here i have assumed that A is the value intially fed to nand gate and than number of nand gates required to get A. 0 votes 0 votes Please log in or register to add a comment.
