hi
aim getting 0-10v from vacuum sensor. It is fluctuating
How to remove the fluctuations from the signal. This signal aim giving to AD571 ADC.
Due to fluctuations display is showing wrong readings.
What hardware I have to use to remove the fluctuations.

A simple resister in series and a capacitor to ground on before the A/D. The values depend on how quick you need it to respond. 10K and 0.1uF will allow your signal to stabilize in 5mS which should be quick enough. depending on your signal you could up the value of one of them 10 times.
A fluctuation by itself doesnt make to qualify your reading as wrong.
Are fluctuations real? Have you checked that?
If so, better you take them into consideration.
Many parameters of a dynamic system, do fluctuate. What matters also is if you want to record the trend of change or actual values and the time interval between measurmements.
