In the following Matlab routine:

=%***********************************************

% BandPass Filter

%***********************************************

Wn = [1.5, 9]/(Fs/2);

[b,a] = ellip(6,0.1,40,Wn);

data = filter(b,a,fr_in);

%***********************************************

%*******************************************

% Plot the rms of the compressed data

%*******************************************

cdata = zeros(length(data),3);

cdata(:,1) = ecompand(data(:,1),255,32768);

cdata(:,2) = ecompand(data(:,2),255,32768);

=

If any, which constants can be treated as variables and changed

slightly? And if so, what are some good bounds? Also, are there any

relationship between them that I should keep in mind (e.g. if I lower

one I have to increase another by xx percent, etc.)

Ok, maybe not-so-qick question...

Thanks,
