Mastering EMC One Level at a Time

LEVEL 6 - Crosstalk in Transmission Lines

This page is a work-in-progress. Please check back later. 

  • Crosstalk due to Common-Impedance Coupling
  • Crosstalk due to Electric-Field Coupling
  • Crosstalk due to Magnetic-Field Coupling
  • Crosstalk in Matched Transmission Lines
These topics are worth reviewing if they were not part of your university education or if you are not completely comfortable with them. Once you've mastered these essential engineering fundamentals, you're ready to move to the next level.

  2. coax with shield grounded at source location
  3. twisted wire pair with one wire grounded at connector
  4. coax with shield grounded through a 5-mm pigtail
