Transmitter power is not the sole issue, but rather a combination of power and proximity. The lowly cell phone a few inches away may cause more problems than the broadcast transmitter a mile away. The ...

Last, but not least, we like to look at the I/O (Input/Output) circuits during EMI circuit board reviews. As a port of entry for external currents, I/O circuits are particularly vulnerable to threats ...

Though often used as synonyms, Electromagnetic Compatibility (EMC) is really the controlling of radiated and conducted Electromagnetic Interference (EMI); and poor EMC is one of the main reasons for ...

Electromagnetic far field impedance is about 377Ω = 120π or 29,9792458 × 4 × πΩ for the vacuum velocity of light. Any electromagnetic wave far enough from its source (rule of thumb >wavelength/2 × π) ...

Many designers think meeting the worldwide safety standards for power supplies in mains-powered products involves following a simple checklist to ensure their designs don’t run into distribution ...

Once relegated to test labs and engineering courses, electromagnetic forces have lately captured the imagination of the masses. Some of this is due to a kind of apocalyptic fascination—the idea of a ...
