Sawtooth wave with offset#

float uz_wavegen_sawtooth_with_offset(float amplitude, float frequency_Hz, float offset)#

Returns one sample of a sawtooth wave with an configurable offset.

Parameters:

  • amplitude – Amplitude for the sawtooth wave

  • frequency_Hz – Frequency for the sawtooth wave in Hz. Only positive values are permitted

  • offset – Offset for the sawtooth wave

Returns:

Returns one sample for current system time
