% User tips:
% 
% 1. All changes to edit box parameters are activated with 
%    the Enter key.
%
%    n  = anti-aliasing filter order (0 = no filter)
%    Fc = anti-aliasing filter cutoff frequency
%    N  = number of bits of precision of ADC
%    Vr = reference voltage of ADC
%
% 2. To change the sampling frequency, use the slider bar.
%
% 3. For the User-defined input, you must supply the file
%    name of an M-file function that returns the analog 
%    input signal value x_a(t).  For example:
%
%    function x = userfun (t)
%    x = t .* exp(-t);
