Generators.nsm
The diagram has two generators, one for rectangle wave and one for sine wave. The signal from sine wave is subtracted from signal from rectangle wave and the result passes through a low frequently filter. The input of filter is shown on Scope with red color; the output is shown with blue color.
The process in this diagram works in process modeling mode. In this case the processor works on a high load. At my computer, it makes 202170 calculations of process per second, which is visible at TextOut control ProcessFrequence.
