Plot may not see features with the default number of PlotPoints.  When you
suspect additional features should be present, increase the number of
PlotPoints.

Plot[{UnitStep[Sin[x] - 6/10], Sin[x] - 6/10}, {x, 0, 60}, PlotPoints -> 100];

In Mathematica 4.0 for windows I use

Plot[{UnitStep[Sin[x] - 6/10], Sin[x] - 6/10}, {x, 0, 60}]

but it seems that some of the pulses are missing, as for x=27 where
UnitStep[Sin[27] - 6/10] =1

Please give me an explanation. >>
