The Tutorial: S Transform
نویسنده
چکیده
The S transform is variable window of short time Fourier transform (STFT) or an extension of wavelet transform (WT). It is based on a scalable localizing Gaussian window and supplies the frequency dependent resolution. In this tutorial, we introduce the fundamental function of S transform and the generalized S transform. Furthermore, we present some applications of S transform: seismogram analysis, analysis of engine induction noise in acceleration, and power quality analysis. Then compare the result of S transform with other time-frequency analysis and exhibit some different windows of S transform.

متن کاملMRI Reconstruction Using Discrete Fourier Transform: A tutorial
The use of Inverse Discrete Fourier Transform (IDFT) implemented in the form of Inverse Fourier Transform (IFFT) is one of the standard method of reconstructing Magnetic Resonance Imaging (MRI) from uniformly sampled K-space data. In this tutorial, three of the major problems associated with the use of IFFT in MRI reconstruction are highlighted. The tutorial also gives brief introduction to MRI...
متن کاملA Tutorial of Integer Transform
The integer transform (such as the Walsh transform, the Haar transform) is a discrete transform that all the entries in the transform matrix are integers. For software and hardware, the integer transform is much easier to be implemented because there is no real number multiplication, but performance is not guaranteed. By contrast, the non-integer transform (such as the DCT, the DFT) has higher ...
