WebSep 30, 2024 · Two robust signal processing techniques, i.e., floor spectral ratio and random decrement method, were implemented. • The NSCs showed a considerable influence on the modal properties and vulnerability index. • The influences of NSCs should be basically considered and systematically applied in the structural models. WebThe biggest limitation comes from the noise floor of the spectrum analyzer. As shown in the equations, when Noise Figure is low (sub 10dB), (P OUTD - Gain) is close to -170dBm/Hz. Normal LNA gain is about 20dB. In that case, we need to measure a noise power density of -150dBm/Hz, which is lower than the noise floor of most spectrum analyzers. designer of firefighter thermal helmets
