Sawtooth wave is generated with ChucK. The aim is to observe the harmonic tones are folded by the nyquist frequency. The frequency of the sawtooth wave was swept up to show the relation between the harmonic tones and nyquist frequency. You can see the harmonic tones rose up and folded at the nyquist frequency. At last the base tone went up beyond the nyquist freuency.

Sampling rate of DAC was set at 5.5kHz and Nyquist frequency was 2.3kHz.
