Hi Julius,
there is an undefined function called "db" (marked below). I guessed it
could be implemented like:
%function db(a,b)
% min(20*log10(a),b) ;
%endfunction
but I dont know octave. Can you provide the function definition?

Hi Urban,
You surmise correctly. Here is my implementation:
function [xdb] = db(x,mindb)
% [y] = db(x,mindb)
% convert x to db, optionally clipped to mindb
ax = abs(x);
xmax = max(ax(:));
if nargin<2, xmin = xmax*eps; else xmin = 10^(mindb/20); end
xdb = 20*log10(max(abs(x),xmin*ones(size(x
