Alternative Method to Estimate the Fourier Expansions and Its Rate of Change by Rodríguez Maldonado, Johnny, Posadas Castillo, Cornelio, Zambrano Serrano, Ernesto

“…This paper presents a methodology to obtain the Fourier coefficients (FCs) and the derivative Fourier coefficients (DFCs) from an input signal. Based on the Taylor series that approximates the input signal into a trigonometric signal model through the Kalman filter, consequently, the signal’s and successive derivatives’ coefficients are obtained with the state prediction and the state matrix inverse. …”
