Spurious emission definition

Spurious emission. In every modulation process additional undesired signals exist. They are summarized 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. 1.145 of the ITU Radio Regulations).

Examples of Spurious emission in a sentence

  • Observation 6: Spurious emission requirements shall be added for NS_[xx] and NS_[yy] in accordance with EN 303 687.

  • Meanwhile, the transmission bandwidth configuration values proposed in table 6 are applied to Spurious emission and Wide band Intermodulation requirements.

  • Proposal 2: Spurious emission requirements for band n40 frequency range when band n41 transmitting power: We support the tentative agreement of -40dBm/MHz which is found in [1] from RAN4#98-e.

  • But it should be noted the more stringent requirement between OBUE and absolute ACLR requirements finally apply for repeater if the assumed output power of gNB is less than 15dBm/MHz. R4-2112766 NTT DOCOMO Observation 1: Spurious emission requirements for IAB-MT are the same with that of BS including regional difference.

  • Corresponding requirements including OBUE and Spurious emission should be defined with the applicability in term of frequency range to comply with ITU decision 2.

  • Spurious emission: Emission 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 emission Ligado Networks: Need clause 6.5.3.3 as there are additional SEM requirements (due to regulatory requirements) for n255 that also apply to Band 255.

  • Spurious emission The spurious emission from the NorDig IRD to the network, as measured at the antenna input connector, shall be less than 34 dBμV over the range 5MHz to 65MHz and less than 30 dB μV over 65 to 862 MHz. Generally, spurious emission should not affect the sensitivity of the receiver.

  • As illustrated below, the isolation can be obtained through: • Antenna spacing• Guardband• External filters Based on previous studies between LTE and GSM, the isolation requirement for spurious emission and receiver blocking are: • Spurious emission: 105 dB• Receiver Blocking: 59 dBIn order to reach such isolation, a >10MHz guardband would be required.

  • Spurious emission from the EUT is measured in the frequency range of 30 MHz to 1000 MHz using a tuned receiver and appropriate broadband linearly polarized antennas.
