Voltage Controlled Oscillator
Description
The Voltage Controlled Oscillator block, typically used for modulation applications. Takes the control input and generates a sine tone at particular frequency.
Usage
The input to the control pin could be varied from 0 to 1. VCO linearly interpolates its derived value into frequency from 0Hz (when input is 0) to FS/2(when input is 1). Where FS is the sampling frequency.
If the input applied is greater than 1, the derived output value will fold back to frequencies below fs/2.
