Every time you generate discrete noise samples (Using MATLAB's randn/ randfor instance) you actually generate a band limited noise. All you need to do is the adjustment of the variance of the discrete samples to the variance of the "Continuous" noise those samples are allegedly taken from.
Noise typically appears as random variations superimposed on the desired echo signal received in the radar receiver. The lower the power of the desired signal, the more difficult it is to discern it from the noise. Noise figure is a measure of the noise produced by a receiver compared to an ideal receiver, and this needs to be minimized.
To produce the correct intensity of this noise, the covariance of the noise is scaled to reflect the implicit conversion from a continuous PSD to a discrete noise covariance. The appropriate scale factor is 1/tc, where tc is the correlation time of the noise. This scaling ensures that the response of a continuous system to the approximate white ...
tests but are unable to reach a conclusion owing to the high degree of noise in the picture. The Bayesian technique of de-noising using Ising priors can prove to be quite handy in such a scenario.

The SBIR and STTR programs fund a diverse portfolio of startups and small businesses across technology areas and markets to stimulate technological innovation, meet Federal research and development (R&D) needs, and increase commercialization to transition R&D into impact. RandStream.setGlobalStream(RandStream('mt19937ar','Seed',1984)); sets the randsom stream to a particular state. (1984 because this is the most True state). Make sure you run this before every invocation of rand:
Project SEIZMO is a Matlab and GNU Octave based toolbox encompassing a collection of over 700 functions that provide a framework for seismic data preparation, quality control, and analysis akin to that of Seismic Analysis Code with a focus on passive source seismology at regional and global scales (where earthquakes and ambient noise are the ...
All seeds from 0 to 1 million would be a good start so I wrote a MATLAB script that generated 10 random numbers for each seed from 0 to 1 million and saved the results as a .mat file. A subsequent Python script loads the .mat file and ensures that numpy generates the same set of numbers for each seed.
