Re: frequency counter

Original poster: "Jim Lux" <jimlux@xxxxxxxxxxxxx>

Counter circuits abound (and, for that range, things like BASIC Stamps and
PICs can count it directly)..
Lots of <$20 multimeters have frequency counting capability these days

Important things to know..
1) What's the input waveform look like?  Nice Square wave or something
really weird, like a tesla coil waveform
2) What kind of output do you need?  display, parallel interface, IEEE-488
3) What kind of accuracy do you need?  1%, 1Hz, ??
4) Do you need a circuit that you can put into a larger system, or is it a
standalone widget
