Ramp Function and Sawtooth Waveform

Consider a ``ramp'' function, having incremental values from 0 to $ N-1$:

\scalebox{0.7}{\includegraphics{eps/ramp.eps}}

Values played sequentially can be used as indeces to read the wavetable.

To loop the wavetable (restart once ended), use a periodic ramp function (positive-valued sawtooth wave):

\scalebox{0.7}{\includegraphics{eps/ramploop.eps}}
