The resulting limit, given in units of bits per second, is the absolute maximum rate of error-free communication given signal strength and noise level.

在给定信号强度和噪声水平的情况下，以比特每秒为单位给出的最终限制是无差错通信的最大绝对速率。

This paper introduces one item named variance rate of gray level and improves the maximum-minimum method by simplifying the noise examination process for suppressing the random impulsive noise.

引入灰度变化率的概念，并据此提出了一种去除随机脉冲噪声的改进算法，将其用于噪声点的检测，简化了最大-最小值方法中的噪声检测过程。

Besides being almost as thin as a credit card (not really), this award-winning ultracompact boasts a pretty impressive set of features, including a maximum ISO of 4000 (no word on noise at that level, however), 2.5-inch LCD, and Super Shake-Free image stabilization.
