Could someone please tell me the difference between analog ground and digital ground on pcb?
It would be easier if you explained it with a example!

Source: Where to put regulator when separating analog and digital grounds?
Some designers like to separate digital and analog sections. There are some parts that even have an analog ground and digital ground. This is to prevent return currents from devices in the digital section creating 'ground bounce' on sensitive devices in the analog section.
In a schematic, usually the grounds will be indicated with different symbols and net names on the schematic, and a net tie is used to join them together.

I took a look at schematic for a digital cameras (from TI) and found that there are different grounding. Will check it later.
