Are you saying in your last paragraph that on a digital circuit for every 2
pulses in I can get 3 out? If so that would seem to be the easy way to go.
Would it work over the frequencys I require say 0.4 kHz to 7.5 kHz (400 to
7500 rpm) and at the 5.5v signal input and output? Would this be done using
gates?
