I built a simple circuit to collect information from a speed sensor, the signal is a sinusoidale signal between 0 and 10 volts. I converting it first to a 0 to 5volts signal before feeding it to an ADC.
However the signal is really sensible to the noise as you can imagine, and i am wondering is there is any way to remove/reduce its influence ?
for information: the requirement is that i should not act on the speed sensor at all ( I am collecting the speed of a shaft in a gearbox, so the speed sensor is already implemented inside). I would like to protect the signal once it is connected to my small board.
If anyone as an idea or recommendation it would make my day :)
