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.
