When noisy data corrupted by colored noise are used, a model is still possible.

The procedure is very effective when the background noise is white and less so when the background noise is red.

Low-frequency intensity noise induced by Brillouin scattering may limit the generation of ultra-low noise signals in optoelectronic oscillators and may limit the transfer of ultra-low noise signals in fibers.

Media noise did not increase with increasing frequency, suggesting that the transition noise was low.

Among photosensitive devices in use today, the photomultiplier tube (PMT) is a versatile device providing extremely high sensitivity, exceptionally low noise and ultra-fast response.

With the proposed technique, the dedicated LNA demonstrates the advantages of self-packaging, compact size, ultra-low noise figure of 0.7/1.1 dB, and rather high power gain of 28.4/28.8 dB at 2.45/5.25 GHz, respectively.

When this FM–AM conversion is the dominant noise source, the noise spectrum of the transmitted intensity can be dramatically altered by the optical-pumping process.

This preliminary study is a step forward towards development of an ultra-low noise SC source at 1300 nm for ultra-high resolution OCT.

This module was shown to outperform existing methods, particularly when noise is taken into account.

When it is used with MED, the resulting output has a nearly ideal blue noise characteristic.

It was found that confocality minimizes the background noise and considerably improves the signal-to-noise ratio when applied to ultramicroscopy.

When used as a photon counting system, the X-ray color sensor has a very high signal to noise ratio, since it removes electric noise in the low energy spectrum during the analysis process.

A purposely designed ultra-low noise preamplifier and the use of an optical link between the PC and the low noise section, has allowed to obtain a total background noise which is some orders of magnitude lower than that of preexistent instrumentation.

Those existing methods can only work when the characteristics of the colored noise are perfectly known.

It may also simplify the noise evaluation by enabling the generation of two or more distinct ultra-low noise RF signals from different optical references using a single OFC and their direct comparison to assess their individual noise.

In this paper we propose a simple design of a fully differential input ultra low noise amplifier with noise performances, in term of equivalent input voltage noise, comparable to those of the best single ended input amplifiers for low frequency noise measurements reported in the literature.
