Should it not be S0S1 instead of S1S0 (as mentioned in the solution). 0 votes 0 votes Shaik Masthan commented Nov 1, 2018 reply Follow Share sorry, i didn't seen the select lines, due to generally they assign A to S1 and B to S0. but in this question, they assigned in the reverse manner. The order of select lines is confusing me. Should it not be S0S1 instead of S1S0 (as mentioned in the solution). it is always like MSB is S1, and LSB is S0 0 votes 0 votes kapilbk1996 commented Nov 1, 2018 reply Follow Share it is always like MSB is S1, and LSB is S0 Could you provide any reference for the same. 0 votes 0 votes Utkarsh Joshi commented Nov 1, 2018 reply Follow Share So the answer given by Shaik Masthan is correct, isn't it? 0 votes 0 votes Shaik Masthan commented Nov 1, 2018 reply Follow Share nooo... I treated S1= A and S0 = B but in the question, S1= B and S0 = A 0 votes 0 votes shubh199815 commented Nov 3, 2018 reply Follow Share kapilbk1996 The evaluating function which u gave seems incorrect. 0 votes 0 votes shubh199815 commented Nov 3, 2018 reply Follow Share kapilbk1996 Moreover the answer which u gave is actually the max terms and not the minterms. According to me, f = {1,3,7,8,12,13,14,15} would be the answer. 1 votes 1 votes Shivam Kasat commented Nov 13, 2018 reply Follow Share I am getting the answer in minterms as f={1,3,7,8,12,13,14,15}. Correct me if I am wrong! 0 votes 0 votes Shaik Masthan commented Nov 18, 2018 reply Follow Share the required function is if F(A,B,C,D) = ∑m(1,3,7,8,12,13,14,15) if F(B,A,C,D) = ∑m(1,3,4,11,12,13,14,15) it is responsibility of the questioner which function is he/she required ! 0 votes 0 votes Please log in or register to add a comment.
