Can someone explain what changes if I use a hi-low vs low-hi circuit for my optical sensor input as seen here?:

It seems to me that it would just invert the signal and I would end up with different trigger teeth or a different trigger angle, no?
If it matters, I am using a DIY autotune trigger disk in a Nissan 240sx KA24DE distributor/CAS.
Thanks for the help!

Either one will work when using our disc. You are correct that it just changes the trigger angle. (If the slots are different lengths, though, it's another matter.)

Thanks for the help! I was trying to figure out why it existed if it just inverts the signal - different length pulses makes sense. Thanks!
