we are now better at dealing with spurious sync pulses
caused by noise, so allow an attenuated control channel.

Ahmet Inan 35994cdfd9 use an modified baseband delay demodulator 
we are working at sampling rate, so we can use a faster approximation and avoid trigonometric functions altogether.
we still have to normalize the output though.
