Andy, You said, "Seems to be a common theme here. Is everyone in the SI community doing computer design??" Nope, Part of my work is EMC with high energy power conversion equipment with power levels approaching 500kW. I find the discussions here often useful. What do I do...? "I specialize in work few understand." "My job is to remove a few unwanted microvolts of RF." "I work in EMC, a black art which is the study of circuits the engineer neglected to put in the schematic (e.g. parasitics)." Thanks, -doug Doug Powell, Staff Engineer Corporate Compliance Dept.
