SineOsc

A source unit that can generate a sinusoid or sine wave. The signal is remapped to oscillate between 0 and 1 (rather than -1 and 1 as the traditional sine wave).

Example

Pulses an LED.

#include <Plaquette.h>

AnalogOut led(9);

SineOsc osc;

void begin() {
  osc.frequency(5.0); // frequency of 5 Hz
}

void step() {
  osc >> led;
}

class SineOsc : public Osc

Sine oscillator. Phase is expressed as % of period.

Public Functions

SineOsc(float period = 1.0f)

Constructor.

Parameters:: period – the period of oscillation (in seconds)

virtual void period(float period)

Sets the period (in seconds).

Parameters:: period – the period of oscillation (in seconds)

virtual void frequency(float frequency)

Sets the frequency (in Hz).

Parameters:: frequency – the frequency of oscillation (in Hz)

inline virtual float frequency() const: Returns the frequency (in Hz).

virtual void amplitude(float amplitude)

Sets the amplitude of the wave.

Parameters:: amplitude – a value in [0, 1] that determines the amplitude of the wave (centered at 0.5).

inline virtual float amplitude() const: Returns the amplitude of the wave.

virtual void phase(float phase)

Sets the phase (ie.

the offset, in % of period).

Parameters:: phase – the phase (in % of period)

inline virtual float phase() const: Returns the phase (in % of period).

inline virtual float get(): Returns value in [0, 1].
