I had put together a simple detection system using an optical incremental encoder system, the output is a voltage signal which corresponds to the displacement.
however, after some studying at this output signal I found the noise to be higher than I wanted. It is currently at 50mV and I wanted it to get down to 5mV. As I need to sample this voltage and process it in a PC and the DAQ card has a resolution of 8mV.
The voltage singal (not including the noise) is not going to be changing at a rate higher than 20kHz.
Are there any processing chip I can readily buy, which will attenuate this noise level?
Many thanks first for any help :lol:
