I'm still not totally clear on what kind of *signal* you want to produce, or whether you describe a temporal *behaviour* of your system.
What aspect of your implementation are you currently working on? The Energy Detector/pass-through functionality? Best regards, Marcus PS: I think you've described your thing pretty well, I'm just not getting it, sorry. I think at this point, a drawing with a few annotations of what your system should do would do wonders, because then we'd have something clear to refer to when discussing!
