The only one I've seen that made real sense is Yaskawa's. They have a 3-channel encoder with transitions of about the same rate on each channel. But, the phase of the C channel varies with octant, so it provides commutation information if the motor is moved only a couple encoder counts. This requires an absolute minimum of signals, except for schemes that encode the information in a serial stream or something like that.
