spurious response

spurious response

[′spyu̇r·ē·əs ri′späns]
(electronics)
Response of a radio receiver to a frequency different from that to which the receiver is tuned.
In electronic warfare, the undesirable signal images in the intercept receiver resulting from the mixing of the intercepted signal with harmonics of the local oscillators in the receiver.

Also, the spurious response occurs far beyond twice the resonant frequency of the resonators, and the out-of-band rejection has been improved.
Frequency splash could either be a selectivity issue (depending on how narrowly-designed the band width is for each frequency) or another issue called spurious response, which is the receiver's ability to reject harmonics.
Huang, 2007) have designed the triple EBG structures for a band stop filter, but there was a spurious response and passband ripple in their performances.
10, the spurious response around 9[f.sub.0] is suppressed after the L slot lines added.
It can control spurious response by changing impedance ratio ([W.sub.in]/[W.sub.out]) of the nested SRR unit cells.
The unique design of the piezoelectric seismic system ensures that the units have no discernible spurious response to mounting torque, body strains, cable vibration, cable whip, pressure variations, and most heat transients.
Keeping the spurious response of a radio receiver down to a minimum is a major problem, particularly in the presence of strong signals to which the receiver is not tuned.
The jitter is <1 ps, phase noise <-80 dBc/Hz (100 Hz offset) at 622.08 MHz, and spurious response <-70 dBc.
It is summarized that this presented filter has the best suppression of spurious response in LF band, high miniaturization level and reasonably low passband IL.
Therefore, the design of DBBSF with individually controlled stopbands and improved spurious response remains challenging.
Table 1 compares the sizes and harmonics characteristics of the proposed resonator of other published works with simultaneous size reduction and spurious response suppression in reference.
6, the asymmetric open-stubs and rectangular micro-strips are introduced to generate transmission zeros around 3[f.sub.0] and 5[f.sub.0] ([f.sub.0] is 2.43GHz), respectively, while L slot lines can give a great suppression to the spurious response around 7[f.sub.0], 9[f.sub.0] and 11[f.sub.0].
