IMHO, it really doesn't matter. It's easy for a single chip computer
to do the detection:

             S   0        1    S
         ..__     ........_____    ...
             |   ^        ^    |   ^
             V___|........|    V___|.. 
            T0       T2       T3

            t1-t0 > t3-t2 => 0
            t1-t0 < t3-t2 => 1

(excuse the notation...) Without doing the math, I suspect this is a
Bayes detector for these data. I can post the C code I'm using if
interested. It uses the 332's TPU to "time stamp" transition times
and make the above decision.
