frequency to voltage conversion
frequency to voltage conversion
(OP)
hello,
I am doing a freq-voltage conversion. But need to design a feedback element in the design loop(f/v converter)to control the frequency. Do anyone have suggestion?. Is there any realisation software to check a digital output(after converting 0-10v to required digital signal through DAC).
Thanks

RE: frequency to voltage conversion
You need to explain your problem in greater detail. It appears that you're using an FVC and an ADC to drive a digital meter (no micro-P involved), and that you wish to incorporate feedback in order to control the frequency you're measuring. Is this correct?

Thanks for the reply. yes I need to control the frequency that I'm measuring. The freq is the output from the sensor interface connnected to a AC motor.What element must be incorporated in the feedback loop of thr F/V converter so that I can control the frequency.
