    I have 2 74LS293 cascade together. Z1 is a MOD 7 and Z2 is a MOD 12. Would that make it a MOD 84 counter? Then I have 930kHz applied to Z1, and I know that my output freq is fin/MOD#. For Z1 would it be fin/MOD 7 or 84? Then to get my other output freq would I divide by 2?
    Thanks in advance.

    1. Fin/7 = ? That is the output of Z1

    2.(Fin/7)/12 = ? That is the output of Z2

    3. You have stated no condition for the "other output freq".
