Spurious emission
In radio communication, a spurious emission is any component of a radiated radio frequency signal, the complete suppression of which, would not impair the integrity of the modulation type, or the information being transmitted.<ref>47 USC §97.3(43)</ref> A radiated signal outside of a transmitter's assigned channel is an example of a spurious emission.<ref>Rudolf F. Graf, Modern Dictionary of Electronics, 7th ed., Woburn, Massachusetts: Butterworth-Heinemann, 1999, p. 724</ref> Spurious emissions can include harmonic emissions, intermodulation products and frequency conversion products.<ref>ITU, 1.145 Spurious emission</ref>
