Zusammenfassung:The methods of numerical signal differentiation are discussed. The convergence conditions for numerical differentiation are formulated. The approach to numerical signal differentiation is generalized based on regular local interpolation with generalized polynomials. The coefficients of optimal differentiators are determined using numerical-analytical methods. Various methods of numerical differentiation are subjected to comparative analysis. The results are implemented in practice.
