need to generate a signal as attached.

Hi all,

I will get my input samples as shown in attached figure.

So to check with that, i need to generate the samples as shown in attached figure.

It has samples with unequal spacing and unequal amplitudes.

I need to generate a signal like the attached figure.

Could anyone plz help me out in generating the signal as shown in attached figure.

It looks like a mass spec or something similar. To create a realistic version, you’d have to know the process that created it, and have some sort of model.

If you just want a random simulation, this will work:

x = 0:399;
xp = sort(randi(400, 1, 19));
y = zeros(1,400);
y(xp) = rand(1, 19)*3;

figure(1)
plot(x, y, '-r')
text(xp,y(xp), cellstr(strsplit(num2str(1:19,'%d '),' ')))  % Add Numbers To The Peaks

NOTE: Any resemblance to an actual mass spec (or whatever your plot is) is entirely coincidental!
