### Generation of i.i.d gaussian random process

```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.

Yes.

This should have been covered in your textbook or

What have YOU done to solve them?

Gaussian process is an infinity Gaussian variables, where each corresponds to a specific instant in time.

A white noise is very trivial to generate because you only need to do is to generate the same random variables independently in time.

Thank you very much for your replies. 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

First of all, you say it is a question, but it is not.  A question has
a question mark, but this is simply a statement copied directly from
"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:

And BTW, the possessive form of its has no apostrophe.  The apostrophe
only appears when it's short for it is.
