Generation of i.i.d gaussian random process
in [Matlab]

From: kalyan on 24 Apr 2010 15:45 Hi all, Could any one help me out in generating gaussian random process using Matlab. I know that gaussian random variable can be generated using "randn", but how to generate a gaussian random process. Is it the same thing. And after generating a i.i.d gaussain random process i need to show it's spectrum is white. please help me solving these two problems. Thanks for your help

Is it the same thing. Gaussian process is an infinity Gaussian variables, where each corresponds to a specific instant in time. > And after generating a i.i.d gaussain random process i need to show it's spectrum is white. > please help me solving these two problems. A white noise is very trivial to generate because you only need to do is to generate the same random variables independently in time. Bruno

But I am sorry that I did not ask the question clearly. Actually the question is: "Generate i.i.d gaussian random process and show that it's spectrum is white(pseudo)" What is the command in matlab to generate a random process? And how do I need to show that it's spectrum is white? Thank you for the help

A question has a question mark, but this is simply a statement copied directly from your homework assignment: "Generate i.i.d gaussian random process and show that it's spectrum is white(pseudo)" How to generate a random process? As John has suggested, read your lecture notes. And this question makes no sense to me: And how do I need to show that it's spectrum is white? Firstly, it's has no apostrophe in this context: it's only has an apostrophe when it's short for it is. But what does this mean: "how do I need to show.."? Maybe you mean "why" instead of "how"? Well, you should ask your lecturer, not us. As for a white spectrum, have a look at this website: http://justfuckinggoogleit.com/ And BTW, the possessive form of its has no apostrophe. The apostrophe only appears when it's short for it is.
