Often, elements used for discrimination are present at concentrations near the detection limit of the EDS system, and the decision whether to utilize these minor peaks in a comparative analysis has generally been left to the discretion of the examiner. The use of signal-to-noise ratios (SNRs) ...
When expressed in dB, a positive number means the signal is greater than the noise and anegative numbermeans the noise is greater than the signal. Some typical dB ratios and their corresponding linear values are given inTable 2.3. Table 2.3.Equivalence Between dB and Linear Signal-to-Noise R...
Phase-stepping(PS) is a widely used method to retrieve information, while angular signal radiography(ASR) is a newly established method. In this manuscript,signal-to-noise ratios(SNRs) of ASR are compared with that of PS. Numerical experiments are performed to validate theoretical results. SNRs ...
Furthermore, the performance loss of one-bit radar detectors proposed in [12] is only 2 dB (π/2) at low signal-to-noise ratios (SNRs), which can be compensated via increasing the number of samples by a factor π/2. These merits motivate the application of one-bit sampling techniques ...
examples taken from this study are shown inFig. 6, where the denoising abilities of different techniques can be observed when applied to noisy recordings with different signal-to-noise ratios (SNRs), namelySNR=0 db and SNR=10 dB. When compared to the presented NLM and EMD-wavelet methods, ...
Do the signal-to-noise ratios presented by instrument vendors accurately reflect improvements in mass spectrometers? We review factors influencing the validity of vendor SNR specifications, and argue that the statistical alternative of instrument detection limits is more consistent wit...
The BERs for different signal-to-interference ratios (SIRs), signal-to-noise ratios (SNRs), numbers of interfering users (NoI), and modulation types of interfering users will be investigated to evaluate the performance. Results In this section, we compare the performances of the different methods...
Fig. 7. An illustration of different signal-to-noise-ratios (SNRs) in the red rectangular regions of three hyperspectral datasets. (a) MV dataset. (b) XS dataset. (c) SY dataset. The red rectangular parts are water nourished by vegetation. Because of the different levels of nutrition, the...
(SNR) associated with one or more impulse or burst noise events, which may be estimated, different respective processing may be performed selectively to differently affected bits associated with the signal. For example, two respective SNRs may be employed: a first SNR for one or more first bits...
The prior art solution presented by Pan, et al., aims to measure wavelength dispersion on transmission paths. Signal degradation is caused not by dispersion alone but it is also necessary to take account of deterioration of optical signal-to-noise ratios (SNRs). In this respect, the quality ...
