Abstract
Eigenfilter method has been recently proposed for designing higher-order differentiators very effectively. The design method is based on the computation of an eigen-vector of an appropriate real, symmetric and positive-definite matrix. The elements of this matrix is usually evaluated by very time-consuming numerical integration. In this paper, we present simple analytic closed-form formulas to compute these matrix-elements very efficiently. Hence the eigenfilter approach for differentiators becomes much easier and more accurate than before, also the design time is reduced greatly with the larger filter length. © 1992 IEEE.
