2.2
Interference source
An interference source is an electrical device or electrical equipment which emits electromagnetic
interference. We can differentiate between two main groups of interference sources corresponding
to the type of frequency spectrum emitted
RF generators
Medical equipment
Data processing systems
Microwave equipment
Ultrasonic equipment
RF welding apparatus
Radio and TV receivers
Switch-mode power supplies
Frequency converters
UPS systems
Electronic ballast circuits
Fig. 5
Interference sources with discrete frequency spectra (e.g. high frequency generators and micro-
processor systems) emit interference energy which is concentrated on narrow frequency bands.
Switchgear and electric motors in household appliances, however, distribute their interference en-
ergy over broad frequency bands and are considered to belong to the group of interference sources
having a continuous frequency spectrum.
