Sine wave with offset#
-
float uz_wavegen_sine_with_offset(float amplitude, float frequency_Hz, float offset)#
Outputs one sample of a sine wave with the specified offset for the current global system time at each function call.
- Parameters:
amplitude – Amplitude for the sine wave
frequency_Hz – Frequency for the sine wave in Hz. Only positive values are permitted
offset – Offset for the sine wave
- Returns:
Returns one sample for current system time
Example#
1#include "uz_wavegen.h"
2int main(void) {
3 float amplitude = 6.0f;
4 float frequency_Hz = 5.0f;
5 float offset = -5.0f;
6 float output = uz_wavegen_sine_with_offset(amplitude, frequency_Hz, offset);
7}
Description#
This function calculates a sine wave with \(y=sin(2 \pi f \cdot t) + x\) where \(t\) is the global system time and :math`x` is the offset.
