The first two sidelobes of the power spectral density corresponding to the 1REC pulse are lower than the first sidelobe of the power spectral density corresponding to the 1RC pulse. This is explained by the fact that the peak frequency deviation for the 1RC pulse is twice that for the 1...
The proper calculation of RMS values of vehicle response for an assumed road power spectral density is explained by an example.doi:10.1076/vesd.35.6.409.2039B. R. DAVISA. G. THOMPSONTaylor & Francis GroupVehicle System DynamicsDavis, B. R,Thompson, A. G.Power Spectral Density of Road ...
Amplitude modulation (AM) effects due to resonant tank dynamics are counteracted by the use of uniquely shaped modulating waveforms, resulting in the elimination of power spectral density (PSD) distortion and reduced peak currents. Emphasis is placed on shaping the inverter or ballast output ...

Broadband PLC modems estimate the DSL-to-PLC channel interference and adapt the PLC’s transmit power spectral density accordingly. Moreover, a considerable effort has been made in PLC focused on the physical layer to deal with issues such as the time-varying behaviour of loads in electric ...
where the process U(t) is a zero mean white Gaussian process with power spectral density N0, bandlimited to (−W2,+W2). We can view the noise process U(t) as a baseband noise process that is translated to the carrier frequency and placed in the passband of the channel. ...
STOs with a 30° and 60° IPPA show a 2–3 and 5–6 times higher efficiency in the power spectral density of the main peak than that with the traditional 0° IPPA, respectively. This increase of the power efficiency with IPPA for STOs can be explained by the power dependence on the ...

Radiant powerW,measured in watts, is the total amount of energy emitted by alight sourceper second. The spectral variation of radiant power can be specified in terms of the radiant power density per unit wavelength intervalWλ [44]W=∫0∞Wλdλ ...
current density from 3.95 V to 4.2 V with decreasing device size. This trend might be explained by improved current spreading uniformity in smaller devices. However, identifying the precise physical reasons requires further investigation, which is beyond the scope of this study....
