Appendix C: Mathematica/Matlab Examples

Below is the Mathematica code for creating the aliasing example in Fig. 8.9.

aliasShow[freq, srate, options___] :=
   SeqPlot[Sin[2 [Pi] freq t / srate], {t, 0, srate-1},options,
    Continuous->True]


a = aliasShow[1, 10]; b = aliasShow[-9, 10, PlotStyle->RGBColor[1,0,0]]; Show[a, b, AspectRatio->13];
