The signal package is required at least for running demo_wfbt:

  >> demo_wfbt
warning: the 'resample' function belongs to the signal package from 
Octave Forge
which you have installed but not loaded.  To load the package, run 'pkg
load signal' from the Octave prompt.

Please read <http://www.octave.org/missing.html> to learn how you can
contribute missing functionality.
warning: called from
      __unimplemented__ at line 524 column 5
      demo_wfbt at line 62 column 3
error: 'resample' undefined near line 62 column 5
error: called from
      demo_wfbt at line 62 column 3

So for smooth running of all scripts in this package octave-signal is 
indeed required. I am not sure whether it is sufficient for adding a 
dependency.
