DISCRITIZATION OF WAVELET FUNCTION FOR COMPUTATION OF DERIVATIVE

M aurice Hasson and Rajendra Pandey have constructed wavelet function using Gaussian function and Maxican Hat function. Richardson extrapolation technique has been used in their constructions. There wavelet functions are applicable for computation of derivatives. In this paper, the authors have derived the discrete analogue of the wavelet function which can be applied to determine the first derivative of function. The discrete version is use full for better approximation of derivatives and the estimate of error can be analysed properly.
