Hi, Claude,
  I came up with something similar, a random walk biased towards 0, as
a signal object.  The parameters are awful tricky/finicky.  I don't
have any good guidelines for choosing the parameters to make it work
more effectively, just trial and error.
  The patch simulates a 1st order stochastic differential equation (in
a crude fashion).  If anyone can suggest a good way to simulate these
kind of equations, I would like to know more :)
