We show that the time-frequency distribution of the fractional Fourier transform of a function is a rotated version of the distribution of the original function, if the kernel is rotationally symmetric. Thus, the fractional Fourier transform corresponds to rotation of a relatively large class of time-frequency representations (phase-space representations), confirming the important role this transform plays in the study of such representations.EnglishTime frequency analysisFourier transformsKernelOptical signal processingOptical computingQuantum mechanicsWavelet transformsNeural networksChirpSignal processing algorithmsArticle10.1109/97.4842111558-2361
