Mistakes & Misconceptions

In this session, we list the design mistakes that led to catastrophic project failures and common misconceptions that even the best engineers in the field think are true.

“It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.”

Mark Twain

M&M 1 – Earth is an infinite sink for noise

M&M 2 – Conducted emission is caused by current in the conductor

M&M 3 – Inductors are inductors, capacitors are capacitors

M&M 4 – The green and yellow wires are essential for EMC

M&M 5 – Multiple ground helps separate noise coupling

M&M 6 – I have a top end spec oscilloscope, and I believe what I see

M&M 7 – Use ferrite beads help reduce noise
