Not sure if this is OT for this list...
In isolating an analog (PLL, VCO, Amps, etc.) section from an otherwise
high-speed digital board I've encountered recommendations to build the usual
PI filter using an inductor (about 10uH) in one case and a ferrite bead (100
to 300ohm) in the other.
What are the merits of each approach?
Thanks,
