return path low impedance
Hello, In many circuits for lowering noise it has been advised to use multiple grounds, one for each segment of board and then connect them together at power supply ground. One problem rises with this scheme and that is some signals have to go from one segment to another segment, though usually this signal lines carry tiny amount of current but it also has been advised that ground return path of each line should not be discontinued anywhere. Can this be a problem, if so how should it be resolved or it can be overlooked because of tiny amount of current that signal lines carry?
Thanks
