The basis of the modular transmission analysis is, that in many practical assignments of tasks the required arithmetic procedure can be subdivided in accordance with the structural construction of the respectively existing transmission into a linear sequence of relatively simple subtasks, that are solely required with other data and where appropriate in other sequence, but in substance homogeneous also in other transmissions and other calculation tasks. The standard provides a system of compatible calculation modules in form of prepared formula theorems. It shows theoretically and by practical examples how these can be combined to complex computation modules.
