N2 - A method which can be used to design lowpass nonrecursive linearphase digital differentiators is described. The method involves formulating an error function based on the absolute mean-square difference between the amplitude responses of the practical and ideal differentiators as a quadratic function. The filter coefficients are obtained by solving a system of linear equations. This method leads to a lower mean-square error and is computationally more efficient than the eigenfilter method and the method based on the Remez exchange algorithm.
