On the Designing of Fractional Order FIR Differentiator Using Radial Basis Function and Window
Authors: Manjeet Kumar, Tarun Kumar Rawat
Abstract: The previous work in [1], Tseng et al. have designed a fractional order differentiator using radial basis function by directly truncating the coefficients to approximate the fractional order derivativeD® of the given digital signal. This paper presents the designing of fractional order differentiator using radial basis function and window. Three design examples are given to illustrate that the use of window along with radial basis function method, improve the frequency response characteristics and minimize the integral root square error than the existing radial basis function method.
