In rotating machinery analysis, tachometer signals are often collected. If a 1 pulse per revolution tachometer is sampled at the same frequency as the vibration signal, then there is some jitter in the tachometer signal. Smoothing cubic splines are a preferred method of removing this jitter. This makes the data being smoothed one dimensional but not uniformly spaced.
I notice that Julia has a number of packages that will perform smoothing splines. Interpolations.jl, Splines.jl, Dierckx.jl, jipolanco/Bsplinekit.jl, SmoothingSplines, Cubicsplines, and maybe more. I would prefer a pure Julia solution. I thought someone might be able to guide me as to which one/ones I should start with.
Thanks in advance for any tips.
