A Digital , Noninteger Order , Differentiator using Laguerre Orthogonal Sequences

  title={A Digital , Noninteger Order , Differentiator using Laguerre Orthogonal Sequences},
  author={Guido Maione}
— This paper presents a novel procedure to design a digital, noninteger order, differentiator. The method is based on the Laguerre series expansion. Firstly, a discrete equivalent of the noninteger derivative Euler backward operator is given in the z-domain. Secondly, this operator is expanded into a Taylor series, which provides the data for the approximation of the Laguerre noninteger order digital derivative operator. Simulation results show the accuracy of the approximation, by measuring… CONTINUE READING
