If You Don’t Like Modeling with a Computer, Try Using Tape and Foil
I am so excited! My son Roger, a Sophomore in engineering, is learning how to make models in JMAG for his internship. He was talking about what great insight a mathematical model gives, and I said that it was possible to make a physical model (a scale model) instead. In the old days, it was quicker and gave different insight than a mathematical model imparts. An old physical … [Read more...]

Proposed Changes to CISPR SC I Standards
Are you familiar with CISPR 32 and CISPR 35? CISPR 32 was originally published in 2012, followed by a pair of corrigenda and then the 2nd edition was published in 2015. CISPR 32 replaced CISPR 13 (Broadcast receivers emissions) and CISPR 22 (ITE emissions). In the EU CISPR 32 is published as EN 55032 and it has superseded EN 55013 and EN 55022. By now you should all be … [Read more...]
