The absolute level of neuromotor noise in the velocity profiles, as measured by power spectral density analysis, was significantly higher in children with ASD; relatively higher neuromotor noise was found in bands >3 Hz. Our findings suggest that significant instability of fundamental handwriting ...
For small analog input signals (on the order of -35dBFS), the thermal + quantization noise power dominate the ADC noise floor, which is used to approximate the ADC's effective noise figure (NF). Once the ADC's NF is known, the cascaded noise figure equation¹ can be used to determine...
We find that assuming a power spectral density with power law slope of -2 at 15 GHz and -1.5 at gamma-ray energies, 7 of our objects show cross-correlations at the 3sigma level. We are now studying the physical significance of these correlations by further exploring the range of power ...
For example, intense ionospheric currents can cripple ground-based power systems (Cid et al., 2020; Oughton et al., 2018), highly energetic electrons in the Earth's radiation belt can lead to satellite anomalies and even complete failures (e.g., Berthoud & Agass, 2022; Green et al., ...
In the z-domain, this becomes Q(z) = (1 - z-1 )E(z) , and in the frequency domain, after z is replaced by ej2nrr , the power spectral density (PSD) of the output noise is found to be (1.4) t. More precisely, the DAC operation is affine, rather than linear. Since the ...

In other words, as the power spectral density decreases, the narrowband noise becomes broadband noise; sideband energy is introduced, the noise floor increases, and the harmonic peaks associated with the characteristic wave are reduced. In general, EMC standards for conducted emissions set peak- ...
