You might like to go to www.analog.com and download application note AN-280
"Mixed Signal Circuit Techniques". It explains many of the low noise
design techniques used in MOTM such as EMI prevention using ferrite beads,
proper shielding, PCB ground planes, etc. It also includes a discussion on
star grounding, and will give you a better appreciation of your MOTM system.
