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

Listing 69 Example function call to sawtooth wave generator

#include "uz_wavegen.h"
int main(void) {
   float amplitude = 10.0f;
   float frequency_Hz = 5.0f;
   float output = uz_wavegen_sawtooth(amplitude, frequency_Hz);
}

Description

This function calculates a sawtooth based on the global system time.
