Why there the multiplexer delay is not taken? 0 votes 0 votes aambazinga commented Dec 14, 2018 reply Follow Share because comparator delay is very large as compared to MUX's, hence, if not given the delay of MUX in the question, we can simply ignore it. i guess that would be the case in the questiton. 0 votes 0 votes Please log in or register to add a comment.
