Which effect can be seen in the eye diagram below?
On the right you can see the time and frequency behavior of raised cosine functions with different roll-off factors - which line corresponds to a roll-off factor of 1? Which line corresponds to a roll-off factor of 0? Why are the raised-cosine and the square -root-raised-cosine functions so useful for communications?
Why is Nyquist criteria 1 not sufficient? Which roll-off factor would you choose based on the Nyquist criteria 2?
Name an example for two orthogonal signals.
Which degrees of freedom can be used for multiplexing? Name and explain the different options.
