| |The voltage-controlled oscillator block, typically used for modulation applications, takes a control input signal (red pin) and outputs a sine tone at a particular frequency on the blue pin.|{{ :resources:tools-software:sigmastudio:toolbox:sources:vco003.jpg}}| | The Voltage Controlled Oscillator block is typically used for modulation applications. The block has a control input signal (orange pin) which specifies a frequency. The blue pin generates a sine tone at the appropriate frequency. |

| The input value may be from zero to one (5.23 format), and the VCO linearly interpolates its derived value into an output frequency from 0 Hz (0.0 input) to fs/2 (1.0 input). Fs is the sampling frequency. | The input value may be from zero to one (5.23 format, or on ADAU145x/ADAU146x, 8.24 format). |

| | The VCO accepts values from 0 Hz (0.0 input) to Fs/2 (1.0 input). Fs is the sampling frequency. The algorithm linearly interpolates the input value into an output frequency. |

| If the input applied is greater than 1, the derived output value will fold back to frequencies below fs/2. | Note that if the input is greater than 1, the derived output value will fold back to frequencies below Fs/2. |

| To change the source's Sampling Rate, Right-click in the block and select Set Sampling Rate, which will open the Sampling Rate window (default is 44.1 kHz). | === Example Schematic === |
