(a) Derive the formula for the power spectral density of a transmitted signal using the 2B1Q line code.

(b) Plot the power spectrum of the following line codes

  • Manchester code
  • Modified duobinarv code
  • Bipolar return-to-zero code
  • 2B1Q code

Hence compare the relative merits of these line codes for their suitability in a digital subscriber loop.
