-|The voltage-controlled oscillator ​blocktypically 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 ===
