% Demonstrate the designLCBP function

fprintf(1,'\t\t\t Continuous-Time LC Modulator Design\n\n');
%WARNING: designLCBP is very ill-behaved due to deficiencies
% in MATLAB's constr() and minimax(). These functions frequently
% take a viable set of parameters as a starting point and turn
% them into an unstable modulator. I should provide a more robust
% implementation...
