摘要: In this paper we propose a modification to second order approximation of the fractional-order Laplacian operator, sα, where 0 < α 1. We show how proposed can be used change ripple error both magnitude and phase responses when compared ideal case. Equal-ripple that have less cumulative maximum deviation are presented using modification. A 1st lowpass filter with fractional step 0.8, is 1.8, implemented approximation. Experimental results verify operation in realization filter.
