They’ll always update on the clock edge triggering positively/negatively. 1 votes 1 votes o commented Feb 2, 2022 reply Follow Share shouldn’t this be considered though ?

If your doubt is why is it taking long for the signals to propagate, it is only due to the number of flip-flops. 1 votes 1 votes palashbehra5 commented Feb 3, 2022 reply Follow Share https://www.youtube.com/watch?v=suE5xUagIBU 1 votes 1 votes o commented Feb 3, 2022 reply Follow Share Oh! this cleared my error in thinking, thank you so much sir, and sorry for bothering 1 votes 1 votes palashbehra5 commented Feb 3, 2022 reply Follow Share i am an aspirant bro :P 1 votes 1 votes Please log in or register to add a comment.
