- Daniel Colls - Parallel traces are often susceptible to cross-talk. These should be separated by at least 2 trace widths for cross-talk reduction. when talking about Circuit Layout.
- Andrew Bylard - Use a stripline circuit when you have two parallel ground planes to give enhanced noise immunity against the propagation of radiated RF emissions.
