A simple and accurate analog to digitaltransform (ADT) is employed, to design a first order digital differentiator, whichclosely approximates the analog one. This transform has a fractional parameterm that our approach design based on. The proposed digital differentiator isobtained by selecting the best parameter m such that the relative error betweenthe analog differentiator s and its equivalent digital one is minimum. Somedesign examples are illustrated to show the effectiveness of the ADT designtechnique. The beauty of this design is that it's only of first order and suitablefor real-time applications.
