对于一个白色高斯噪声源来讲,研究频率范围内噪声功率谱密度的均匀性就说明了噪声源的“白色”程度,而其峰值因素常说明了高斯电压幅度的分布情况。峰值因素(简称RMS)被定义为电压峰值与电压平均值的比值。如果噪声源的峰值因素低,那么,通常不会发生超过特定峰值的电压偏差。电压偏差常使得误比特
For a white Gaussian noise source, the uniformity of noise power spectral density in the study frequency range shows the “whiteness” of the noise source, and the peak factor often shows the distribution of Gaussian voltage amplitude. The peak factor (referred to as RMS) is defined as the ratio of the voltage peak to the voltage average. If the noise source has a low peak factor, then voltage deviations above a particular peak will usually not occur. Voltage deviation often makes bit error
