VCO - Voltage controlled oscillator. Produces a sinusoid of frequency based on the amplitude of the input. See VCO for a real (not complex) sinusoidal output.
input: float stream of control voltages;
output: complex oscillator output
Parameters
- Sample Rate
- sampling rate (Hz)
- Sensitivity
- units are radians/sec/(input unit)
- Amplitude
- output amplitude
Example Flowgraph
This flowgraph shows a Radioteletype (RTTY) transmitter and receiver. The upper portion is the transmitter. The parameters for the VCO are explained in VCO.
The lower portion of the flowgraph is a single sideband (SSB) receiver. The audio can be fed into a RTTY decoder such as shown in Sample_Rate_Tutorial#Source_hardware_example.
