% Explanation of the input parameters: 
% 
% xi_t: deterministic process or time-domain signal to be analysed  
%       with respect to the average duration of fades T_(r) 
% r: equidistant level vector 
% T_sim: duration of the simulation 
% PLOT: plot of the resulting average duration of fades T_(r),  
%       if PLOT==1 
 
function adf=adf_sim(xi_t,r,T_sim,PLOT) 
 
cdf=cdf_sim(xi_t,r);
