Created a 3b rollback counter for my intro to digital logic class. I derived the functions for J and K of each JKFF memory elements just using k-maps from the inputs of A2, A1, and A0. Surprisingly, the circuitry for a 3b counter with JKFFs is actually much more simple than it was for DFFs. This is because each operation works with two of the 4 possible JKFF operations, so half of the k-map inputs were don't care conditions. This allowed the circuitry to be simplified so much further that there are only 3 gates for the whole circuit excluding the rollback output.
