multiply circuit?
(OP)
I have a /3 then /5 circuit (4017, 74HC90) for reading Rev/S on a pump shaft. Now I have a new indicator which cannot be changed, that must see 4 signals per revolution. The exciter is 35-1 teeth. Can I multiply by four? I apologize, I have not had formal training in this field.
Thank you very much
Thank you very much





RE: multiply circuit?
If I understand, you divide the output by 3 and then by 15
-- i.e. alltogether by 15 --.
In this case you could get more evenly distributed pulses
by taking the signal before dividing by 5 and skip
one of five pulses.
Do you get 35 pulses/rev ? in this case you must divide by
7 and 5 -- i.e.35 -- not by 3 and 5. In this case it would
be better to divide by 9-9-9-8.

This will give to you allmost evenly spaced pulses.
