* I need to ask if i have a PCB board with analog and digital circuits, is it's right to connect the digital and the analog GND to the GND layer or i must create two Gnd layers and connect them at the Gnd entery point to the board.
* I need to know how can i select the value of my fuse instaled on the primary side of 220 VAC transformer to compabtible with the UL standard. I have a board with transformer of 12 VA and 220 VAC input and it uses a fuse 3.15 A how the designer of this board select this fuse.
Waiting for reply
With my best regards
