Frequency counter

Hey Folks
was wondering if a Frequency counter, can count frequencies of only digital signals, or analog signals as well. I have an analog (sine wave) whose frequency is to be read. Is it possible to use a Frequency counter straight for this operation (if yes, which one) , or the signal has to be converted to a square wave first and then read using a counter ?

Thanks
Shreyas

Hi,

I think that as long as the waveform changes direction regularly, your counter will work with it. Freq counters were originally made to count analog waveforms.

Hey BeenThere
Thanks for the reply. Shall try rigging up the circuit now.

The signal has to be converted to a square wave vave. All modern Frequency counters are digital.

You sure about that, Dragon? Methinks u've a bit more learning to go.
