Re: Colored Noise in Matlab

Started by rizw...@yahoo.com March 31, 2009
Hi tarang ..
i need a bit more elaboration on colored noise ..
can u please give a small code which can generate colored noise ??
thanx in advance

Ali

Can anybody elaborate on this.if h(t) is the impulse response of the filter I have to send white Gaussian noise to it,in continuous domain .In matlab simulation I have to generate a vector of Gaussian random variables using randn and convolve it with the discrete filter coefficents and use each element of the output vector as one time instant value.Is it correct
