Fractional Order Derivative Filter Design Using Fourier Transform Interpolation Method
نویسنده
چکیده
Fractional order derivative is one of the important techniques for the designing of fractional order filter such as differentiator and integrator. Three basic approaches that are used for the design of the fractional order differentiator namely: discretization method, interpolation method and approximation method. All these method provide a great degree of approximation to the designed filter such that it approximates the ideal filter response. Here, in this paper interpolation method for the designing of fractional filter is presented. Different interpolation techniques are presented and studied. Keywords— DFT, FFT, Interpolation

A New Implicit Finite Difference Method for Solving Time Fractional Diffusion Equation
In this paper, a time fractional diffusion equation on a finite domain is con- sidered. The time fractional diffusion equation is obtained from the standard diffusion equation by replacing the first order time derivative by a fractional derivative of order 0 < a< 1 (in the Riemann-Liovill or Caputo sence). In equation that we consider the time fractional derivative is in...

In this paper, the computation of a fractional derivative using the Fourier transform and a digital FIR di!erentiator is investigated. First, the Cauchy integral formula is generalized to de"ne the fractional derivative of functions. Then the fractional di!erentiation property of the Fourier transform of functions is presented. Using this property, the fractional derivative of a function can be...

متن کاملFourth-order numerical solution of a fractional PDE with the nonlinear source term in the electroanalytical chemistry
The aim of this paper is to study the high order difference scheme for the solution of a fractional partial differential equation (PDE) in the electroanalytical chemistry. The space fractional derivative is described in the Riemann-Liouville sense. In the proposed scheme we discretize the space derivative with a fourth-order compact scheme and use the Grunwald- Letnikov discretization of the Ri...
