–5 votes –5 votes Lets explore the answer As we know: TT = framesize/Bandwidth; and minimum time taken to acquire the line is = 2*pt TT = 2*pt min frame size = 2*pt*b.w; =200 bits(C) Sachin Tripathi answered Jul 4, 2016 Sachin Tripathi comment Share Follow See 1 comment See all 1 1 comment reply Rakesh K commented Sep 29, 2016 reply Follow Share The answer will be 200 bits, not bytes. hence option D). 3 votes 3 votes Please log in or register to add a comment.
