Velocity Circuit
Velocity Circuit
(OP)
Hi, I have a signal coming out of a potentiometer that tells the distance traveled in voltage. Is it a position transducer which outputs voltage when a cable is pulled.
My question is, how do I go about using that distance travelled to get a velocity output in voltage?
For example, 0 - 1000 rpm, output = 0-5V.
I would probably need instanteneuos velocity? Do I get that by diffentiating distance/time? Use op-amps?
Thanks.

RE: Velocity Circuit
Since you are starting with an analog... it would probably be best to stay with analog... and use Op Amp(s) to get your derrivative.
