ENCODING EMISSION, IMPULSE That emission produced by impulses hav- ing a repetition frequency not exceeding the impulse bandwidth of the receiver in use. EMISSION, PARASITIC Electromagnetic radiation from a trans- mitter that is not part of the information signal or harmonically related to the carrier, caused by undesired oscillations in the cir- cuitry. EMISSION, RADIATED Desired or undesired electromagnetic energy propagated through space. Such an emission is called radi- ated interference if it is undesired. EMISSION SPECTRUM A power versus frequency distribution of a signal about its fundamental frequency, which includes the fun- damental frequency and the associated modulation sidebands, as well as nonharmonic and harmonic emissions and their associated sidebands. EMISSION, SPURIOUS Any electromagnetic emission on a fre- quency or frequencies that are outside the necessary emission band-
