The oscillation frequency can be controlled by the clock frequency divided by 100 (eg 10 kHz clock frequency generates 100 Hz waves).

# Working principle
# Working principle
The mathematics behind the functioning of the system lies in the design of marginally stable discrete systems (that is, with simple poles present in the unit circle of the Z plane). The system works from a simple IIR filter with outputs that have an impulse response equal to sine and cosine.
