[Bertho] sent in a great tutorial on terminating transmission lines. If you’ve ever tried to send a high frequency signal a long way down a wire, you know the problems that can crop up due to ...

At high frequencies (e.g. microwave) the physical dimensions of printed circuit board (PCB) traces become significant relative to the wavelength of the signal. At these frequencies, controlled ...

Introduction to electromagnetic waves in electrical engineering. Topics include: concepts of transmission lines, electrostatics and magnetostatics; Maxwell's equations for time-varying fields; ...
