Let the transmitter pulse
be the NRZ pulse given by
 Draw an eye diagram corresponding to the signal at the input to the linear receiver.
 Draw an eye diagram corresponding to the signal at the output of the linear receiver.
 Based on these eye diagrams, explain why the NRZ pulse is both a Nyquist pulse and a squareroot Nyquist pulse.

 Express the three waveforms in Figure 2.23 (page 46 of the Anderson text) in terms of an orthonormal basis. To do this problem, apply the GramSchmidt procedure outlined on pages 4445 of the text.
 Draw the vectors in signal space. Your drawing should look something like Figure 2.25 (page 47).
 What is the dimension of signal space in this problem?
 Draw the orthonormal basis functions and .

Let
