i have signal between |f|<100 Hz
and i need to present it the range of |f|<125 Hz
MY PROBLEM is that i want to have a continuity between the output signal to the outrange 100<f<125 to be a solid line
in this range the output signal doesnt exist so it just cutted with no bound to x axis

IN SIMPLE WORDS
to add contiuetinity (yellow line to the x axis)
thanks for help!

% Test data
f = (-100:1:100);
p = randn(size(f)); p = p-min(p)+1;
% extropolate data
fe = [-125 f 125];
pe = interp1(fe, [0 p 0], fe, 'linear', 'extrap');
plot (fe, pe)
axis tight
grid on
