17.3 Power Supply Filtering
Ferrite beads are not advisable in digital switching circuits because inductive spiking (di/dt noise)
is introduced into the power rail. Simple RC filtering is probably the best approach provided care
is taken to ensure the IR drop in the resistance does not lower the supply voltage below the
recommended operating voltage.
