Best answer 3 3 votes The given gates are XNOR gate. At the first gate we can see that we have P XNOR 0, which gives 1 if p=0 and 0 if p=1 so we can say that our output from the first gate is P' (P complement). Now this output is fed as a input to the next gate , so we have P ⊙ P' at the next gate. Now P ⊙ P' means the combination will always be either 0 ⊙ 1 or 1 ⊙ 0, so this gate will always give output as 0. So, i/p to the 3rd gate is 0 ===> which is seen like original problem with 22-2 = 20 XNOR gates So, after 2 more gates o/p again 0. Finally, after 2 gates, after 4 gates, after 6 gates....... o/p is 0. there are total 22 gates which are even ===> o/p at the end should be 0 Hirak answered May 14, 2019 • selected May 14, 2019 by Shaik Masthan Hirak comment Share Follow See all 2 Comments 2 2 Comments reply Shawn Frost commented May 14, 2019 reply Follow flag thanks a lot sir 0 0 replyShare Hirak commented May 14, 2019 reply Follow flag I am no sir..just an ordinary guy like u my friend and a gate 2020 aspirant.. :) 1 1 replyShare Please log in or register to add a comment.
