Ultrawide Bandwidth Signals as Shot-Noise: a Unifying Approach

Andrea Ridolfi

We present a shot noise based model for a large family of ultrawide bandwidth (UWB) signals. These include time-hopping and direct-sequence signaling with pulse position, interval, and amplitude modulations. Each specific signal is constructed by adding fe ...

Shot noise perturbations in digital holographic microscopy phase images

Christian Depeursinge, Etienne Cuche, Frédéric Montfort, Florian Charrière

In digital holographic microscopy, shot noise is an intrinsic part of the recording process with a digital camera. We present a study based on simulations describing how shot noise influences the quality of the reconstructed phase images under different be ...

Sampling and exact reconstruction of bandlimited signals with additive shot noise

Martin Vetterli, Pina Marziliano, Thierry Blu

In this correspondence, we consider sampling continuous-time periodic bandlimited signals which contain additive shot noise. The classical sampling scheme does not perfectly recover these particular nonbandlimited signals but only reconstructs a lowpass fi ...

Shot noise influence in reconstructed phase images SNR in digital holographic microscopy

Christian Depeursinge, Etienne Cuche, Pierre Marquet, Florian Charrière

We present a study based on simulations describing how shot noise, an intrinsic part of the recording process with a digital camera, influences the quality of the reconstructed phase images under different beams intensities configurations. ...

Synaptic Shot Noise and Conductance Fluctuations Affect the Membrane Voltage with Equal Significance

Wulfram Gerstner

The subthreshold membrane voltage of a neuron in active cortical tissue is a fluctuating quantity with a distribution that reflects the firing statistics of the presynaptic population. It was recently found that conductance-based synaptic drive can lead to ...

First Fully CMOS-Integrated 3D Hall Probe

Radivoje Popovic, Pavel Kejik, Enrico Schurig

We present the first fully CMOS-integrated 3D Hall probe. The microsystem is developed for precise magnetic field measurements in the range from mT up to tens of tesla in the frequency range from DC to 30 kHz and with a spatial resolution of about 150 μm. ...

Causal coding and feedback in Gaussian sensor networks

Michael Christoph Gastpar

Varaiya and Walrand found an elegant insight regarding the use of feedback in a causal coding context: While generally useful, feedback becomes useless when the channel is sufficiently symmetric. The goal of this note is to extend this insight to scenarios ...

Virtual Sensor Design

Sabine Süsstrunk, Roberto Costantini

We present a virtual digital camera sensor, whose aim is to simulate a real (physical) image capturing sensor.To accomplish this task, the virtual sensor operates in two steps. First, it accepts a physical description of agiven scene and simulates the enti ...
