AES San Francisco 2010
Product Design Track Event PD4

Saturday, November 6, 9:00 am — 10:45 am (Room 132)

Product Design: PD4 - Grounding & Shielding - Circuits and Interference (Part 1)

Ralph Morrison

This first session will discuss the way signals and power are transported. We will discuss the basic meanings of words such as voltage, current, capacitance, and inductance; the role conductor geometries have in controlling where signals and power can travel; the problems of utility and facility design together with the meaning of ground and earth; the interference problems created by transformers and facility wiring; a discussion of shielding as applied to analog circuits and radiating structures. Terms such as differential, balanced, common-mode, normal-mode, and single ended will be explained.
