Sawtooth wave

float uz_wavegen_sawtooth(float amplitude, float frequency_Hz)

Returns one sample of a sawtooth wave.

Parameters:

  • amplitude – Amplitude for the sawtooth wave

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

Returns:

Returns one sample for current system time

Example
