Electric and Magnetic Fields from Simple Circuit Shapes,their associated transmission cables is of paramount importance to proper EMI control. Unfortunately, precisely calculating the fields radiated by a modern electronic equipment is a hopeless challenge. In contrast to a CW transmitter, where the the radiation source characteristics (e.g., transmitter

Fields Radiated by Nonsinusoidal Sources,re sinewave but a repetitive signal with a known period and waveform. This chapter will describe the two most common cases of nonsinusoidal sources: periodic signals with narrowband (NB) spectrum, and periodic signals with broadband (BB) spectrum.

General Strategy for Designing a Low-Radiation Product,switching or continuous wave (CW) devices to be found in any equipment, there is practically no example of a product which, having been designed with complete disregard to these aspects, escapes the certification test with an “O.K.” label. Therefore, for sake of self-compatibility (i.e., no self-jam

Emission Control in Mother Boards and Backplanes,n the design. Although some mother boards contain active devices (bulky discrete components, power supplies, etc.), their major function is to effect interconnection between the daughter cards and with the I/O lines.

Controlling Radiated Fields from Switch-Mode Power Supplies,ast majority of today’s electronic equipment uses this type of regulator. With regard to EMI, this type of power supply has always been a serious concern, primarily because of its conducted emissions but, to a lesser extent, its radiated emissions. The first aspect is covered extensively in Ref. 10,

assessment at the time was that Mr. Fluke had written a very good and useful volume, its only flaw being that it focused on just half of the EMI emissions problem. This, of course, was also its strength; although radiated and conducted emissions do not exist in separate worlds, it can be useful, at
