The signal processing denotes mostly spectral analysis and regeneration using the filtration of the different spectral components. In the last time we use increasingly the numerical processing on dedicated devices or universal calculators. In these cases the mostly usable algorithms are based on the property that values of the signals are discontinuous in the time and consist from discrete samples. In order to obtain correct results using classical formulas as Fourier's transform applied on discontinuous values we need besides known Shannon's theorem another elements, as well as a new theorem which will be presented in this work.
