A zero-mean white Gaussian noise is passed through an ideal lowpass filter of bandwidth 10 KHz. The output is then uniformly sampled with sampling period = 0.03 msec. The samples so obtained would be (a) correlated (b) statistically independent (c) uncorrelated (d) orthogonal |

Answer» (b) statistically independent White noise contains all frequency components, but the phase relationship of the components is random. When white noise is sampled, the samples are uncorrelated. If white noise is Gaussian, the samples are statistically independent |
