Consider a digital transmission system using ook. the received output volt age pulse has a gaussian shape for binary "1" as follows: t2 u(t) = aexp(-202 where a is the peak pulse amplitude and σ is the pulse width at 60.7% level. the pulse is flat0) for binary "o". derive an equation for the maximum bit rate such that the vertical opening of the eye diagram is more than 80% of a. you can assume that the tails from bits that are (7 marks) not adjacent are negligible.

Why are graphs useful when interpreting data

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
