However if you feel it should be, you should challenge. 0 votes 0 votes Please log in or register to add a comment.
22 votes 22 votes I don't know if it makes sense but answer can be 4 if we don't convert the expression in POS form. From SOP form, it will take 4 gates. If the question implies this restriction!

Note:- Minterm and Product term are different. Every Minterm can be Product term but not vice versa. For example, in a 4 variable function, term "BD" is product term but not minterm. Because, Minterms are terms that should contain every variable either in true or complemented form. The term "BD" doesn't contain both A and C either in true or complemented term. Whereas the term "ABCD" is a minterm for a 4 variable function and it is equal to 15. Let's come to the question now. The function is expressed in sum of minterms. Now we have to minimize it. We can minimize it into either SOP or POS as there are no restrictions on the questions. So, using 3 NOR gate, we can minimize. 0 votes 0 votes Please log in or register to add a comment.

Hopefully you will get this If you challenge they have solution which contain 4 gates. iiitnaveen answered Feb 21, 2019 iiitnaveen comment Share Follow See all 3 Comments See all 3 3 Comments reply mradul commented Feb 21, 2019 reply Follow Share 3 will be right answer 6 votes 6 votes Ahabnnc commented Feb 21, 2019 i edited by Ahabnnc Feb 21, 2019 reply Follow Share There is no point of solving it as SOP or POS. The question only said that the function is expressed in SOP form using the given values, they didn't ask you to define a concept and design the circuit in SOP form only. 5 votes 5 votes Himanshu Kumar 1 commented Feb 22, 2019 reply Follow Share Hopefully, you missed out on basics. which Concept says not to use sop or pos while minimizing no. of gates? 0 votes 0 votes Please log in or register to add a comment.

I thought everything will be correct in the key and forgot to check the key released by them. Yesterday only I came to know that answer for this question is wrong. But by yesterday, I couldn't challenge as the time was over. 0 votes 0 votes Please log in or register to add a comment.
