Talk:Sine and cosine transforms

From Wikipedia, the free encyclopedia

Cosine Transform (CT) has been underestimated. Since virtually all physical quantities do not actually require description by negative values but each of them has a natural zero, CT is the tailor made transform if one asks for primary physical reletionships, not the complex-valued Fourier transform (FT). There is no negative distance. Radius, elapsed time, energy, frequency, temperature, charge of an electron, mass, wave length, etc. are also always positive. Cartesian coordinates and the ordinary time demand arbitrary reference points. This redundant information on linear phase is the only one that makes the FT of a function of elapsed time more 'complete' as compared to CT by various immediate and subsequent notorius worries: required double redundancy, non-causality, ambiguity, misinterpretation of apparent symmetry, the need for arbitrary windows in signal processing, etc. Our ears have no knownledge of the zero of time exactly related to Christ's birth midnight New Year in Greenwich. They just relate to the very moment. Performing CT they are able to add a one-way rectification to the motion of basilar membrane according to CT. This would be impossible with FT. Therefore we could not distiguish by ear between rarefaction and condensation clicks. Fortunately, hearing is still much better than the FT and Ohm's law of acoustics allow. What about the outcome of the second expensive in history physical experiment, I am curious. If Higg's boson is an artifact of improper use of FT, then it will never be found.
