From: ben harper on 1 Apr 2010 03:44 I use Band-Limited White Noise in Simulink It needs two parameters: noise power & sampling time. I understand the latter. In help it says that "noise power" is height of the PSD. Is it the variance of the white noise? Because i need to cretae a white noise with variance.. Thank you in advance.

Your terminology is a bit off, but generally, yes, that will be the variance of each random variable in the white noise process. I'm not quite sure I understand what you mean by "create a white noise with variance." -- Idin Motedayen-Aval The MathWorks, Inc. zq=[4 2 5 -15 -1 -3 24 -57 45 -12 19 -12 15 -8 3 -7 8 -69 53 12 -2]; char(filter(1,[1,-1],[105 zq])), clear zq |
