What is power supply decoupling and how can this be eliminated?
 

From your question I would reccomend reading through some of these:

Trace Inductance
 
High-frequency noise on power supplies causes problems for nearly every digital device. Such noise is typically generated by ground bounce, radiating signals or even by the digital device itself.
The simplest method of curing power supply noise is to use de-couple the high-frequency noise to ground via capacitors. Ideally, the de-coupling capacitors provide a low-impedance path to ground for the high-frequency noise, hence ‘cleaning’ the power supply.
