in f to V converter, input is frequencies . Is that electrical or Mechanical frequency?
To convert a frequency to a voltage, you need an electronic frequency (voltage varying in time).
One can use different types of transducers to get an electronic frequency from a mechanical one.
National makes a chip, LM2917, just for this application. Check out "http://www.national.com/mpf/LM/LM2917.html" [Broken] where you can see the transducer (magnetic pick up).
sensor transduces electrical frequencies?
how to convert this frequency to mechanical frequency(RPM),,,
i ve seen a design before, they use scmitt's trigger before f to V converter
i think schmitts dont sense the frequency...(no magnetic pick up)?????
LM2917 only detect positive peak of sinusoidal wave?
