3 votes 3 votes 3 variable function can be implemented with 4*1 MUX or 8*1 MUX. No. Of 2*1 mux reqd to implemet 4*1 is 3 And no. Of 2*1 reqd to implement 8*1 is 7. 7 isn't given in the options. So it shud be 3. Is it ? What's the answer ? PS. Additional circuitry like Not gate might also be needed. saloni answered Jul 21, 2015 saloni comment Share Follow See all 2 Comments See all 2 2 Comments reply shreshtha5 commented Jul 21, 2015 reply Follow Share i am also getting 3 but answer given is 2 :( 0 votes 0 votes sushmita commented Apr 4, 2017 reply Follow Share why not 4?? we will need 3 , 2*1 MUX to implement the above boolean function and one more 2*1 MUX to implement NOT gate. how 2?? 0 votes 0 votes Please log in or register to add a comment.
