O que (quem) é oversampling - definição

PROCESS OF SAMPLING A SIGNAL AT A SAMPLING FREQUENCY SIGNIFICANTLY HIGHER THAN THE NYQUIST RATE

Over-sampling; Oversample

oversampling

¦ noun Electronics the technique of increasing the apparent sampling frequency of a digital signal by repeating each digit a number of times, in order to facilitate the subsequent filtering of unwanted noise.

Oversampling

In signal processing, oversampling is the process of sampling a signal at a sampling frequency significantly higher than the Nyquist rate. Theoretically, a bandwidth-limited signal can be perfectly reconstructed if sampled at the Nyquist rate or above it.

Oversampled binary image sensor

$Fig.1 The imaging model. The simplified architecture of a diffraction-limited imaging system. Incident light field <math>\lambda_0(x)</math> passes through an optical lens, which acts like a linear system with a diffraction-limited point spread function (PSF). The result is a smoothed light field <math>\lambda(x)</math>, which is subsequently captured by the image sensor.$

IMAGE SENSOR WITH NON-LINEAR RESPONSE CAPABILITIES REMINISCENT OF TRADITIONAL PHOTOGRAPHIC FILM

An oversampled binary image sensor is an image sensor with non-linear response capabilities reminiscent of traditional photographic film.L.

Oversampling

In signal processing, oversampling is the process of sampling a signal at a sampling frequency significantly higher than the Nyquist rate. Theoretically, a bandwidth-limited signal can be perfectly reconstructed if sampled at the Nyquist rate or above it. The Nyquist rate is defined as twice the bandwidth of the signal. Oversampling is capable of improving resolution and signal-to-noise ratio, and can be helpful in avoiding aliasing and phase distortion by relaxing anti-aliasing filter performance requirements.

A signal is said to be oversampled by a factor of N if it is sampled at N times the Nyquist rate.
