Every edge transition that is sent from the microcomputer to another chip is a current pulse. The current pulse goes to the receiving device, exits through that device’s ground pin, then returns via the ground traces, to the ground pin of the microcomputer (see Figure 2). The pulse does not exit the ground lead of the receiving device and return to the battery, but travels in a loop to where it originates. Loops exist everywhere. Any noise voltage and its associated current travels the path(s) of lowest impedance back to the place where it was generated. This is a very powerful concept, because it allows you to mitigate noise propagation by controlling the shape and impedance of the return path.
