1D signal approximation

Dear users of CodeProject,

How to get approximated points for 1D Points having only several reference points?
Splines like Bezier are not suitable here.

Applying something like Bezier the dynamic range of the 1D signal changes and I need some approximation without such defect (I mean without changes in dynamic range).

P.S. It should be something in addition to linear approximation.

Thanks in advance!

I don't see a C++ question here.

I do see an open ended mathematics question.

There are an infinite number of ways to derive curves for points. We could probably go off topic, and present some solutions, but it's likely that we'd guess wrong.

I'll try to help though.
Follow these steps and you might get an answer.

1. Identify what the points represent. Everything about these points seems to be a big mystery. We don't know where they come from, what their values represent, or what their values, ranges, limits and distributions are. This is important information, and if you figure this out it will help you a lot.

2. Once you've figured out what the data represents, explore literature that pertains to this type of data.

3. Find the algorithms already in use by professionals that work with this data.

I hope this helps. It's the way I tackle problems of this sort.

Thanks, Jack!

Even for a criticism.)
