When the grounds are different at source and destination, how do you connect the signal source to your circuit?
I know there is a difference in the ground potential of source and destination. But is this treated as noise or just an additional voltage that adds with the source signal?
I thought we could use an isolation transformer or an opto-coupler. But how does the isolation transformer help?
