Question:
What is psuedogaussian noise? I have heard that it is anotherb term for "white" noise.


Replies:
White noise (in the context of sound) is the presence of sound waves of equal intensity for all frequencies (usually in the audible range from about 15 to 20,000 hertz). I assume that "psuedogaussian" noise is the presence of sound waves whose intensity centers about an average frequency and decreases in intensity in a gaussian distribution. That is: ~ exp(-(nu-nu avg.))^2 where nu is the frequency and nu avg. is the average frequency.
