Description: 应用傅里叶变换DFT，分析各种离散信号x(k)的频谱。离散周期信号可以展开成傅里叶级数，所以离散周期信号的频谱 是一个周期的周期性离散频谱，各谱线之间的间隔为 ，而且存在着谐波的关系。 -DFT application of the Fourier transform, analyze discrete signal x (k) of the spectrum. Discrete signal cycle can begin as Fourier series, the discrete signal spectrum is a cyclical cycle of discrete spectrum, the line between the interval, but there is a harmonic relationship.

Description: 离散傅里叶变换是20世纪60年代是计算复杂性研究的主要里程碑之一，1965年Cooley和Tukey所研究的计算离散傅里叶变换(Discrete Fourier Test)的快速傅氏变换(FFT)将计算量从О(n2)下降至О(nlogn)，推进了FFT更深层、更广法的研究与应用。
这是一个傅氏变换的MPI程序，用C语言实现。-Discrete Fourier Transform of the 20th century 60 s computational complexity is a major milestone in one study, in 1965 Cooley and Tukey studied the calculation of discrete Fourier transform (Discrete Fourier Test) fast Fourier transform (FFT) calculation increased from О (n2) dropped to О (nlogn), the FFT to promote deeper, broader research and application of law. This is a Fourier transform of the MPI process, with C language. Platform: |

Description: This paper is a brief introduction to discrete wavelet transform as digital signal-processing
technique and the application. The field of discrete wavelet transform (DWT) is an
amazingly recent one because itÌ s better than Fourier transform. This technique was used on
power system to partial discharge site location. Partial discharges are caused by various
defects such as voids, shield protrusions, contaminants, advanced stages of water tree, etc
and known the main cause of breakdown in insulation materials. Platform: |

Description: Wavelet Toolware is a companion software package to the book An
Introduction to Wavelets by Charles K. Chui. It is designed for the
reader to gain some hands-on practice in the subject of wavelets. The
objective is to provide basic signal analysis and synthesis tools that are
flexible enough for the reader to easily increase the capability of the
Toolware by adding processing algorithms to tailor to specific areas of
application. Wavelet Toolware contains, among other algorithms and
codes, the one-dimensional (1-D) and two-dimensional (2-D) Discrete
Wavelet Transforms (DWTs) and their inverse transforms, as well as
computations of the Continuous Wavelet Transform (CWT) and the
Short Time Fourier Transform (STFT).-Wavelet Toolware is a companion software package to the book An
