One of the most common uses of wavetable synthesis is to produce sinusoidal signals. In this case, the wavetable holds one period of a sinusoid, as shown in Fig. 1 below.

A sinusoidal wave table.
The sinusoidal oscillator frequency is controlled by the phase increment as described above.
An arbitrary phase offset can be implemented by an initial pointer offset into the wavetable. For example, a phase offset of radians would correspond to a phase increment of 16 samples when the table length is 64 samples.
