I would like to build a frequency divider for bench use and could use some advice. What I would like to do is to use some of the thumbwheel BCD switches that I have (single digit) to make a circuit that would divide by whatever number that the switch displays. So if I turned the switch to 3, it would divide the input signal by 3, 9 would divide the signal by 9, etc. How would I go about doing this? A circuit that would work up to around 20 Mhz would work fine for my use.
