Appendix C: Example MoML Figures 7.11 and 7.12 show a simple Ptolemy II model in the SDF domain. Figure 7.13 shows the execution window for this model. This model generates two sinusoidal waveforms and multiplies them together. This appendix gives the complete MoML code. The MoML code is divided into two files. The first of these defined a component, a sinewave generator. The second creates two instances of this sinewave generator and multiplies their outputs. The code listings are (hopefully) self-explanatory. C.1 Sinewave Generator The Sinewave component is defined in the file $PTII/ptolemy/actor/lib/Sinewave.xml, which is listed below. This file defines a MoML class, which can then be referenced by the class name ptolemy.actor.lib.Sinewave. The Vergil rendition of this model is shown in figure 7.11. This composite actor generates a sine wave. The sampling frequency, in the same units as the frequency.
