I want to use a sensor with analog output in my design. The output of the sensor is a low frequency traingular wave (less than 300 Hz) and voltage vetween 0 - 5V. I need to carry the sensor signal to the controller through a cable, approximately 400mm in length. The sensor supply voltage and ground line also comes from the controller. I have following questions
- There is a strong noise source (motor windings) close by. How can I improve the noise immunity of the signal carried to my controller?
- The literature I have gone through suggests approaches like shielding, single ended to differential conversion or conversion to current signal. Is there any other approach available for this kind of situation?
