    I need to build a d flip flop asynchronous counter for an exam tommorow, and i was wondering how i would change the wiring because i know how to wire an active high d flip flop counter, but not active low. any help appreciated.

    If you do not wish to use the Q output (active high), then use the not-Q output (active low).

    so on an active high circuit the Q's would be the output, and in a active low the not-Q's would be used?
