I'm examining the signal sent by my cars FOBcar's fob. Using an RTL-STR and GNU Radio Companion, I've been able to capture and demodulate the signal. 

Now I'm working on decoding the signal. What I'm not sure about is whether the signal is just FSK (frequency shift keying) isor if it is FSK with Manchester coding.

Is there a way to tell if a signal is Manchester coded?

Distinguishing simple FSK and Manchester coding?
