I want to use the output value of a signal generator as the delay value of a delay block. Is there a way to pass the output of a signal generator(saw tooth) to the delay block? I have attached an initial grc file and a picture of what I want to do. Any help would be appreciated.Thanks...TomPS Do you know if I need to sign up for any workshops, etc.. at the GNURadio Conference next month or do I just show up and take a seat? I've already registered.
