Abstract

This paper presents analytical study of chirp signal, by taking into consideration the method of Fractional Order Savitzky-Golay Digital Differentiator (FOSGDD). This paper is further used to enhance the performance of the chirp signal. In this method first, moving window coefficients using polynomial least square method and Riemann-Liouville, method is computed. Then the coefficients are used to estimate fractional order derivative of sinusoidal signal and chirp signal. The work proposed in the paper demonstrates that the, Root Mean Square Error (RMSE) and computation time is greatly improved and it can efficiently calculate the fractional order derivative of the noise free signal and noisy chirp signal
