gnuradio-companion - GNU Radio Companion (GRC) is a graphical tool for creating GNU Radio signal

       GNU Radio is a free & open-source software development toolkit that provides signal processing blocks  to
       implement  software-defined  radios  and signal-processing systems. The GNU Radio applications themselves
       are generally known as "flowgraphs", which are a series of signal processing blocks  connected  together,
       thus describing a data flow.

       gnuradio-companion  is  effectively a Python code-generation tool. When a flowgraph is "compiled" in GRC,
       it generates Python code that creates the desired GUI windows and widgets, and creates and  connects  the
       blocks in the flowgraph.

       gnuradio-companion  -  GNU  Radio  Companion  (GRC)  is  a  graphical  tool for creating GNU Radio signal
       flowgraphs.
