Abstract. Derivatives of signals generate spikes if noise is present. This is the typical case in practical applications. This paper deals with an approximation of a derivative using a dynamic system to avoid spike and noise due to the calculation of this derivative. After formulating the problem, a proposition allowing to find a possible solution, which consists of the wanted approximation, is proven.
