    Solution Preview

    The problem with simple techniques is that a higher bit rate requires more signal elements and thus reduces the difference among them. Not only we need fine instruments to measure these differences, but signals become more susceptible to noise. This puts a (practical) limit on number of ...

    Solution Summary

    The solution briefly discusses the issues of bit rate and signal processing circuitry. Digital to analog translations and the advantage of schemes like QAM are determined.
