Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
This flowgraph shows a Radioteletype (RTTY) transmitter and receiver. The upper portion is the transmitter. The parameters for the VCO are explained in [[VCO]].<br>
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]].

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/volt
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.
