Pcb double panel if there is a simulated ground and digital to the two to be split?
The last question, that is, when the shop in the copper, set different types of land, respectively, covering the different needs of the above.
so if you can see the PCB plane a number of areas of copper, and the area by the inductor or resistor connection, it is likely to be different.
they and digital ground will be used inductors or 0 ohm resistance or other means connected to a single location. Some of the analog and digital ground of the PCB is divided into copper,
Of course, some of the situation is present. How to distinguish between what kind of signal, to see the type of device on the board, some analog devices of course to take the analog,
