Materials Engineering: Little-known facts about precious metals
, PMs may be used in large quantities when there is no feasible substitute. The eight PMs gold (Au), silver (Ag), platinum (Pt), iridium (Ir), palladium (Pd), rhodium (Rh), ruthenium (Ru), and osmium (Os) are conveniently grouped together in the periodic table. A subset of this group is called

It is clear that phase noise in the vicinity of this offset will make a significant contribution to the period. jitter. The maximum offset frequency for the purposes of integration is determined by the bandwidth
