I am having some difficulty with type D flip-flops. from my experience in the real world if you tie the notQ output to the D input it will toggle /2 and can be used as a divider. None of the designs listed seem to do the job, so I built my own. If anybody is interested come look at it @ 192.168.1.101:25566
this is my first time 10/5/2011 hope i got it right
