That depends. It would help to see the rest of the schematic. The zero ohm resistor is placed there so that there is an option to have them connected or separate. Normally they would be connected together at the power supply off board, or right at the power connector. The reason for doing this is to make the digital noise travel all the way back to the power supply before having a chance to effect the analog ground.hi,
i have a schematic in which there is digital ground and analog ground symbol as shown below. the analog ground is for mic and speaker. the value of R5 resistor is not given or is zero resistor!!
can i simply connect the analog and digital ground together, that is same potential?
