Simulation of Optical Spatial Filters by Using Fast Fourier Transform

Simulation of Radix-2 Fast Fourier Transform Using Xilinx

The Radix-2 decimation-in-time Fast Fourier Transform is the simplest and most common form of the Cooley–Tukey algorithm. The FFT is one of the most widely used digital signal processing algorithms. It is used to compute the Discrete Fourier Transform and its inverse. It is widely used in noise reduction, global motion estimation and orthogonalfrequency-division-multiplexing systems such as wir...

Determination of Riboflavin by Nanocomposite Modified Carbon Paste Electrode in Biological Fluids Using Fast Fourier Transform Square Wave Voltammetry

Herein, fast Fourier transformation square-wave voltammetry (FFT-SWV) as a novel electrochemical determination technique was used to investigate the electrochemical behavior and determination of Riboflavin at the surface of a nanocomposite modified carbon paste electrode. The carbon paste electrode was modified by nanocomposite containing Samarium oxide (Sm2O3)/reduced gra...

Option Valuation Using the Fast Fourier Transform

This paper shows how the fast Fourier Transform may be used to value options when the characteristic function of the return is known analytically.

Quantum fast Fourier transform using multilevel atoms

We propose an implementation of the quantum fast Fourier transform algorithm in an entangled system of multilevel atoms. The Fourier transform occurs naturally in the unitary time evolution of energy eigenstates and is used to de®ne an alternative wave-packet basis for quantum information in the atom. A change of basis from energy levels to wave packets amounts to a discrete quantum Fourier tra...
