摘要

A digital white Gaussian noise generator based on the Lindeberg theorem is studied. The main novelty of this work is the performance analysis of the noise generator in frequency and time domain. A noise generator (150MHz) is designed and implemented to verify that the wide bandwidth and good gaussian distribution cannot be obtained together when the digital processing speed is fixed. The experimental results showed that the performance analysis is correct, and the experimental range of noise bandwidth satisfying the frequency and time domain performance was also presented.
