Hi,It's digital signals (but might need pull-ups), test with a multimeter.Direction can be seen from which one is going high first.Call them A and B, going in one direction, the signals would look like A-B-/A-/B-A-B etc. while the opposite direction should be B-A-/B-/A-B-A etc.It's quite easy to decode in a µcontroller, but with a few gates you could bang up a circuit to output both pulses and a direction signal.The speed is in the pulsing of either of the outputs giving a certain number of pulses per revolution.
of course multimeters can show analog voltages !!! Multimeters measure a bunch of stuff , one of them being voltage logic probes on the other hand only do digital
They [...] are out of phase by 90 degrees not 180.
I don't have a clue how to interface the encoders with my micro-controller and begin writing code to detect the pulses. Anyone, anyone?
