The mathematical imperfections resulting from the use of different mathematical functions to describe event rates or event densities are considered in this project. For this purpose, a holistic holistic event density function based on mathematical methods is derived from physics and signal theory.It is to be shown that with the new holistic event density the different interference calculations necessary for the load analysis and the response time analysis can be carried out uniformly. Thanks to the novel approach, real-time verification can also be carried out in the frequency domain (Fourier analysis).For task systems with variable event rates, the complexity of the real-time analysis should be drastically reduced. Starting from the idea of modeling the different events and computation time densities with the help of needle pulses (Dirac pulses), it is to be shown that it is possible to formulate a uniform event density for all analysis methods and to simplify such known analyzes. In particular, this applies to the analysis of task systems with variable, frequency-dependent event rates (variable rate behavior, vrb). In addition, efforts are being made to simplify the density function of the hierarchical event streams and to integrate the new event functions or curves into the real-time calculus.
