Figure 1: Intensity noise spectrum of a solid-state laser. Here, the power spectral density relative to that of shot noise is displayed. PSDs can be defined via the squared modulus of the Fourier transform of the quantity of interest, but the straightforward approach works only for functions ...

1.2 Power spectral density (PSD) measurements (peak vs. rms) Mathematically, PSD is the integral of the power spectrum (that is the FTT of the time domain signal) over the frequency domain. Thus, for the „full picture”, the term PSD must include the frequency range it is being invest...
1)computes the Power spectral density and Amplitude spectrum (P(f),F(f)) of 1d signal y(t) with sample rate Fs (Nyquist rate) which is known% apriori. The results are plotted in 3 figures which correspond to simple PSD,logarithmic PSD (dB) and Amplitude Specturm r...
For spectrally-resolved measurements, we send part of the FH light to the optical spectrum analyzer. We calibrate the fiber-to-chip coupling efficiency based on power transmission measurements and fits of theoretical models to nonlinear response data (see “Methods”). The typical edge coupling ...

a wide spectrum of procedures for degradation testing makes it difficult to compare the obtained results, thus makes their practical application unsuitable. In order to systemize the proposed testing procedures, an overview of investigations that include PEM electrolyzer degradation testing is presented he...
(0 ms to 500 ms before stimulus onset) and then averaged across sites on a log scale. The eight colored traces represent the change in power spectrum for eight stimulus orientations. We observed that the mean LFP gamma between 45 to 70 Hz was strongest and fastest at a stimulus ...
