Annotation: The original method of digital differentiation of signals for use in real time is synthesized. The method is based on application of multi-point estimation of unknowns on their experimental measurements and pseudo-inverse matrices. Some results of analytical researches, showing the efficiency of the method are given.

Keywords: digital differentiation of signals, system of the linear algebraic euations, matrix, pseudoinversion (pseudo-manipulation)
