I've done a little with Gnuradio a couple years ago, but I'd now like to apply it to a serious problem.
I
have a design I'm working on that will output raw data that could be
interpreted as an audio stream centered on 1kHz. I'd like to work on
extracting CW signals that are rather slow, from a rather narrow
bandwidth, and see how far down into the noise I can actually extract
the signals.
Is there a block that can bring in CSV data from a file at a specific rate, and serve as the input to my CW detection system?
