Pulse encoders supply a defined number of pulses per revolution.
These pulses are counted in the evaluation electronics. The number of
pulses arriving in a certain period provides a measure for the distance
covered in this time segment.
Most pulse encoders are provided with pulse tracks A and B. These
supply two pulse sequences offset by 90°. By evaluating all edge
transitions, it is possible to duplicate the pulses and increase the
resolution. The sense of rotation can be seen from the time sequence.
In addition to tracks A and B, most pulse encoders also have a zero
track. This provides one pulse per revolution.
