2014年5月7日. A Comparison Between Haar Wavelet Transform and Fast Fourier Transform in Analyzing Financial Time Series Data. S. Al Wadi, Mohd Tahir Ismail and Samsul Ariffin Addul Karim. Abstract: Recently, the Fast Fourier Transforms (FFT) and the Discrete Wavelet Transforms (DWT) are two time series filtering.

Feb 24, 2010. Anyone who deals with financial series knows they are aperiodic (meaning they do not repeat indefinitely). The FFT, or fast fourier transform is an algorithm that essentially uses convolution techniques to efficiently find the magnitude and location of the tones that make up the signal of interest. We can often.

We explore the frequency domain of irregular time series by applying a Non- Uniform Fast Fourier Transform (NUFFT) on Natural Gas Futures prices. We show that High-Frequency Traders are responsible for a growing number of cyclical patterns. In particular, we observe the emergence of a new power law in the Fourier.

One common way to perform such an analysis is to use a Fast Fourier Transform (FFT) to convert the sound from the frequency domain to the time domain. Doing this lets you plot the sound in a new way. For example, think about a mechanic who takes a sound sample of an engine and then relies on a machine to analyze.
