function [slow,fast]=karjalainen1996(insig,fs)
%KARJALAINEN1996  Non-linear adapation network
%   Usage: [slow,fast]=karjalainen1996(insig,fs)
%
%   [slow,fast]=KARJALAINEN1996(insig,fs) computes the non-linear
%   adaptation network from Karjalainen et al. (1996) on the input signal
%   insig sampled with a sampling frequency of fs Hz.
% 
%    XXX What are the assumptions on the input? The example below
%     generates NaN's
%
%    XXX What is slow and fast*? In which units are they defined?
%
%    XXX Which level convention is used ?
%
%    XXX Bibtex entry for the correct paper to cite.
%
%   Examples:
%   ---------
%
%   The following show the adapation to a simple test signal:
%
%     [insig,fs] = greasy;
%     [slow,fast]=karjalainen1996(insig,fs);
%
%     subplot(1,2,1);
%     plot(slow);
%
%     subplot(1,2,2);
%     plot(fast);
