Resistor Value

autodeskguest

Hi,

I was analyzing the schematic attached and found the resistors R51 and R48

marked as "0R". What does that mean? Anybody understand this ?

    I would suggest that the designer has split power supplies. The rest of

    the circuit requires both Vcc and Vdd supplies. For one reason or

    another, these have not all been named as the same net. perhaps one is

    an analogue rail, the other digital. They are brought together where

    these resistors (jumpers really) are on the board. The same trick can be

    used to have split grounds.
