Good evening.
I have a tricky problem to solve, so any advice will help.
I have a circuit that its output is a binary number showed by LEDs (the number represent number of clocks per period, in my case the period is 0.08sec)
I need to convert this number to frequency (clocks).
any suggestions..?

the range is from 10hz to 200Hz

P.S. I need to build the circuit not use an existing component

WhaT?

Are you saying you want to RECREATE an available ICs function with discrete parts?

If so, I would start by reading the datasheet for the HCF4089. On page 3 it shows the logic diagram for the function provided by the IC. You could use that to build a discrete version.
