Calculating Signal To Noise

Only in very simple situations can we describe the correlation between two time series as a single number. Often it varies both as a function of time, and of wavelength. Datasets may be uncorrelated on short timescales due to noise, but strongly correlated on larger wavelengths (eg annual).This...

Bacula Filesystem in USErspace BaculaFS is a filesystem that exposes the Bacula catalog and storage as a Filesystem in USErspace (FUSE). BaculaFS is a tool, independent of Bacula, that represents the Bacula catalog and backup storage media as a read-only filesystem in userspace. BaculaFS is...

The Additive Noise Channel and the Additive Guassian Noise Channel are the simplest of all signal channels.The script mimics any experiments on these channels.

Analog Noise is a VST format plug-in which will add not only the sound, but also the atmosphere of analog recordings to all your mixes. The purpose of the plug-in is to add sounds typically found in the recordings of existing devices. For this goal, Analog Noise has 21 sound profiles, including...

This model uses the NLMS adaptive filtering algorithm to suppress additive noise. It does not require a reference noise signal. However, the noise should be such that the auto-correlation of the noise be close to zero for some lag greater than a certain number. This model implements the NLMS...

Digital noise or Image noise is the most common issue faced by photographs as it makes photos look grainy. Usually a photo clicked in low light conditions or with not so good camera have tiny dots making image look grainy and distorted. This problem can be resolved with Noise Reducer Pro. Noise...

This program converts the noise sidebands to power, adds in an estimate of the power for CW spurs, then calculates the jitter from this. It is not really exact, but it is simple and allows for an easy estimate of the jitter and phase noise without special tools.
