Well, the job of the power squelch *is* to figure out whether the signal
should be passed through, based on the signal itself.

Well, if that signal has energy (as defined by your Energy detector),
yes, I guess.

I don't understand. "The spectrum": What does this mean to you?
Spectrum is usually used as a expression describing the wholeness of
signals in a given frequency range.

So the question is: Your control can be 0 or 1, right? (Please reply
in-line)

Let's define:
n_in = samples going into your "tap"
n_out = samples coming out of your "tap"
n_ctrl = control values going into your "tap"

While the control is 0, do you
a) want your samples coming out of the "tap" to be constant 0, meaning
that n_in=n_out=n_ctr, OR
b) want the samples to just be dropped, n_in = n_ctrl, n_in < n_out;
c) you want your tap to just let samples through when control is 1, so
that it behaves like a real water tap, holding water back, meaning that
n_in = n_out > n_ctrl

> Using a tap was my best explanation for now haha
That's why I still ask you for a quick drawing :)

Best regards,
Marcus
