I want to make a pulse alternator, so when a redstone pulse enters, output A on one side gives out a pulse, and when the second pulse enters, output B on the other side gives a pulse, and when the third pulse enters output A fires again (and so on). But I don't want the outputs to be sustained outputs (like a lever), just 2-4 redstone tick pulses. If anyone knows how to make something that does this, please tell me and screenshots would be appreciated.

A ring: 2 hoppers, 2 droppers, alternating, facing each into another in a circular fashion. Input signal activates the two droppers. Pairs: Comparator + repeater feed outputs A and B out of the hoppers. There's one item in this ring.
(the image shows the base level of the device. You will have connect the blocks marked 'I' drawing redstone between them above or below.)
This will activate the output A or B for duration it takes the hopper to eject the item into the dropper next to it. Next pulse on input I will inject the item into the other hopper. If instead of a ring you use a looping 'pipeline' of alternating hoppers and droppers, you can have as many outputs as you want.
