In the following you can see the channel A ( above ) and the Channel B ( middle) output of an optic encoder that is connected on a rotating shaft.
My questions is: Does the impulse width impact the way you need to count the distance? To me , it seem that channel A is in advance from channel B therefore I just need to add distance to my current total distance ( convention A in avance on B = increment in position)
Could you see it as the distance going back and forward therefore explaining the larger pulse on channel A and smaller pulse on channel B?
[EDIT] Here is the link to the encoder that will be used
