First post here, so sorry for mistakes or inappropriate posting.
This was one of the tasks in a digital logic exam I failed today. The exact request was "Design a synchronous frequency divider to 13(state diagram, truth table, electronic scheme). Draw the signal/time diagram for the outputs Q."
As I understood from the course, frequencies can only be divided by powers of two (2,4,8,16 etc). Is this divider even possible at all? I had no idea even where to start.
