A Photon Imaging Detector Model with High Resolution and High Counting Rate
Applied Sciences, 2023 A cross strip (XS) anode detector is a photon-counting imaging detector with high spatial resolution. However, due to the Poisson distribution characteristics of the photons emitted by the target, photons with a small time interval will cause signal ...

Can a second order bandpass sigma delta modulator achieve high signal-to-noise ratio for lowpass inputs [PDF]
, 2008 Institutively, second order SDMs usually achieve lower SNR than high order ones because high order loop filters can achieve better noise shaping characteristics. Moreover, the signal transfer function should be designed to have large values and the noise

Study of charge collection and noise in non-irradiated and irradiated silicon detectors [PDF]
, 1996 The large collection and noise were studied in non-irradiated and irradiated silicon detectors as a function of temperature (T), shaping time (0) and fluence , up to about 1,2 x 10(14) protons per cm2 for minimum-ionizing electrons yielded by a 106 Ru ...

Using noise to shape motor learning
Journal of Neurophysiology, 2017 Each of our movements is selected from any number of alternative movements. Some studies have shown evidence that the central nervous system (CNS) chooses to make the specific movements that are least affected by motor noise. Previous results showing that the CNS has a natural tendency to minimize the effects of noise make the direct prediction that if
