Look at http://www.roymech.co.uk/Useful_Tables/Maths/fourier/Maths_Fourier_transforms.html and compare the fourier transform of: 1. top hat (sinc) 2. triangle (sinc^2) 3. gauss (gauss)
trapezoidal is inbetween top hat and triangle. for accaleration function 1. top hat: jerc is unboundet 2. triangle and trapezoidal: jerc is constant 3. gauss: jerc is gauss _Conclusion:_ gaussian accaleration gives the _lowest_ frequency components! Unfortunately gaussian jerk is impossible. You have to wait infinite time to start the motion. Which function looks like a gaussian? The sinusoidal type in STR_V8_N1_07_MCH.pdf: Fig.1 (a) or 4267.pdf: page 8, upper trace is a candidate!
