I have many transducers which all have single-ended signal outputs. I hook them up to a single-ended DAQ board. A board with 16 single-ended inputs. The DAQ bard is currently set to single-ended configuration, but can also be set to a differential-ended configuration.
For noise reduction I'm considering to use the DAQ board in differential ended mode.
As far as I know, a differential signal outputs SIGNAL LO and SIGNAL HI electrically floating with respect to ANALOG GROUND.
I some confusion and have the following questions:
1-) Do I need to buy new transducers which output differential signals if I were to use a differential-ended data acquisition board?
2) If so, is there an alternative way to convert a single-ended signal to a differential-ended one?
3-) If I use a differential-ended data acquisition board with single-ended signals without common grounds would it be also OK to reduce the noise?
edit: I think there are transducers which output mirrored signals as SIGNAL LO and SIGNAL HI. And there is also Differential Connection of single-ended transducers which has Signal and GND. This is the source of my confusion.
