No.  The list of problems remaining is:

- 4.7
- 4.9

- 5.5
- 5.6
- 5.11 (omit the plot, just list the main advantage(s) and disadvantage(s)
        of each modulation)
- 5.13 (see Table 1.1, IS-54 $\equiv$ USDC)
- 5.15 (omit out-of-band power computation)
- 5.18
- 5.20
- 5.25
- 5.26

That's 11 problems (2 from Chapter 4, 9 from Chapter 5).  Sorry for
the confusion.

The material for the last two problems had not been covered by
the end of the last lecture and I'd be happy to postpone them to
a later assignment (but nobody has asked me to do this yet).

B is the 3 dB bandwidth of the Gaussian filter (see section 5.5.3
in the book or the bottom of page 1 of the notes for lecture 5)
and T is the symbol period.
