Here's the revised draft for Touchstone 2. The following changes have been made, per team requests: - [Normalization] and the concept of normalization has been ditched for version 2.0 files - the differential data set limitation has been explained (hopefully better) to exclude SDD12, SCD11, etc., but to still permit data sets where pairs of terminals are grouped together as ports PDF copies of both the markup and "clean" versions are enclosed, to make cross-platform viewing easier. Comments are welcome. We will discuss this draft in the next meeting. - MM <<touchstone_spec2_draft4_markup.pdf>> <<touchstone_spec2_draft4.pdf>> <<touchstone_spec2_draft4.doc>>
