Division 8.7.3

‘Spurious emission’: in every modulation process additional undesired signals exist. They are summarised under the expression ‘spurious emissions’. Spurious emissions are emissions on a frequency or frequencies which are outside the necessary bandwidth and the level of which may be reduced without affecting the corresponding transmission of information. Spurious emissions include harmonic emissions, parasitic emissions, intermodulation products and frequency conversion products, but exclude out-of-band emissions (Article 1 No 1145 of the radio regulations).
