Chapter 4 of 4 in the Radial Expert Series on Power & Conditioning, entitled “Electromagnetic Radiation & Interference” is now available for free download (below).
Electromagnetic interference, often referred to as EMI, is a degradation of the performance of a piece of equipment or system caused by electromagnetic radiation. Electromagnetic radiation is the travel of alternating electric and magnetic fields through space at 186,273 miles (about a billion feet) per second, or the speed of light.
Most audio systems are in the nearfield at all frequencies below about 1 MHz, including 60 Hz (hum) and its harmonics (buzz). In the nearfleld, either the magnetic or electric field dominates, and each requires a different kind of treatment to eliminate interference.
The Expert Series on Power & Conditioning is presented by Radial Power and features top authors from ProSoundWeb, Live Sound International magazine, and around the industry.
