% 1. All changes to edit box parameters are activated with the Enter key.
%
%      a   = vector of denominator coefficients, a(1) = 1
%      b  = vector of numerator coefficients
%      c  = damping factor of damped cosine input
%      f aging filter order (0 = no filter)
%      Fc = anti-imaging filter cutoff frequency


% 2. To remove the noise from the signals, set a = 0 and b = 0
% 
% 3. The cosine input has frequency fa Hz.
%
% 4. The pulse input has at 50 percent duty cycle.
%
% 5. The length of the subsequences for power density spectrum estimation is L = N/4.
%
% 6. For the User-Defined input, you must supply the file name of a MAT file that contains
%    the input vector x and the sampling frequency fs.
