SUMMARY

The discussion centers on the presence of "fuzzy" artifacts in the spectrum analysis output of MATLAB when using a Binouli random data source. The user speculates that these artifacts may be due to distortion or noise. However, the response clarifies that randomness is inherent in the data and that one should not expect a deterministic outcome from random inputs. The analysis highlights the importance of understanding the nature of random data in signal processing.

MATLAB! Question!

Hi,

http://www.geocities.com/spoutveg10/matlab.JPG

Does anyone know what the "fuzzy" bit at the tops of the spectrum are? I went for a complete guess out of distortion or noise. Any elaboration as to why?

I connected up a Binouli random data source with a sample time of 1, and added a repeat block (x5) to obtain this signal.


THANK YOU VERY MUCH IN ADVANCE! I APPRECIATE YOUR INPUT!

Wait... you performed some operation on random data, and you're wondering why there is any randomness in the result?

I don't know what to say, except you can't expect randomness not to be random.
