Re: Colored Noise in Matlab

Started by muna...@yahoo.com March 30, 2009
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

Thank You
