I'm examining the signal sent by my car'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) or if it is FSK with Manchester coding.
Is there a way to tell if a signal is Manchester coded?
