Oops. Forgive me for the blank message!
Anyway, I see your picture different. I see a control signal as a
constant sine wave. When you mix the control signal with the data
signal (using a PLL, but that's not important right now) you would get
a null when the signals matched, and a signal when they differed:
1 2 3 4 Time
| | | |
/\ |/\ |/\ |/\ | Control signal
\/| \/| \/| \/|

/\ | /\|/\ |/\ | Data signal
\/|\/ | \/| \/|
0 1 0 0 Resulting Signal
