Hi All,
I need to feed the board power supply via a 3-meter cable(dc power supply is generating on the mother board). I just wonder how can we calculate a suitable de-coupling capacitor value in this situation? We always use a big enough cap and low esr type but is there any proper way to calculate the right value?
Thanks in advance.
